The Dengineers: Community Den Special The Dengineers

-I'm Lauren.

-And I'm Joe.

-And this is The Dengineers.

The show that puts you in charge of building your very own dream den.

Dens for adventure...

CHEERING

..hanging out with your friends and family...

Amazing!

..and dens built to fulfil your dreams.

Amazing, thank you so much.

Whatever your idea, The Dengineers team are here

to transport your inspiration into amazing spaces.

Wow!

Built especially for you.

-ALL:

-This den is done!

Merry Christmas!

Wow!

Waah!

Welcome to a very special episode of The Dengineers.

Yes. Today, we are at a children's hospice on the Wirral

to surprise a group of children with the news they're going to get

-the den of their dreams.

-And strap yourself in,

because this is going to be our biggest build yet.

Today's Dengineers are the amazing folk

of Claire House Children's Hospice,

which is a Children In Need supported project.

Dengineers, we really need your help to build us an awesome den

for our new hospice.

Where we can make lasting memories with our friends and families.

A hospice is a place that provides care for children with life-limiting

conditions and their families.

Ready, Hol?

A big part of what we do

is not just supporting the child, it's supporting the whole family

and that's really important for brothers and sisters.

There's one, Shay.

That support carries on, sadly, when the child dies.

Providing care afterwards is so important.

We used to come to the pool

and we've got videos of Ellie and Mia having fun.

They're memories that are so important to us.

Mia's sister Ellie spent a lot of time here

before she sadly died when Mia was three.

And the hospice has played a huge role in helping her deal with

the loss of her sister.

She can speak to kids who have gone through the same thing

and you can see the fun they have.

It's quite a lonely place if your brother or sister has died

and the hospice really helps them.

You can see that they grow up and it's not a scary thing.

The hospice is opening a brand-new site in Liverpool

so they can reach even more seriously ill children

and their families.

And it just so happens there's an area round the back

that is perfect for a dream den.

The work that we do with these families is all about creating

memories that are going to last a lifetime.

If we could make a den outside for all the children

and their brothers and sisters, it would be absolutely brilliant.

These guys really need our help, Joe.

And that's exactly what they're going to get.

They just don't know it yet.

For today's hit we've come to Hospice HQ, and our merry band of

Dengineers have been busy fitting their super-spying hidden cameras

all over the place.

-I'm a bit nervous.

-I'm excited.

Our Dengineers have started to arrive at the hospice

and Loz and I have the perfect watch-out spot,

just above reception.

There's a lot of them, in't there?

There's, like, parents, siblings...

OK. Thumbs up.

Come on.

Everyone is in position. Time to deliver the amazing news.

Sorry...

Excuse me, hello, everybody.

We've got a little bit of a surprise for you this morning.

Actually, it's a massive surprise.

-My name is Joe...

-And my name is Lauren..

..and we're from CBBC's The Dengineers.

EXCITED CLAMOUR

Now, we have heard that there's a second hospice site being built

over in Liverpool, and you guys are going to need a space where

you can play with each other,

where you can relax and all hang out. Does that sound right?

Yes!

The good news is that's exactly what you're going to get!

CHEERING

Not just that, it's going to be the biggest den we've ever built!

I was so surprised.

I was like this...

I'm so excited.

And it's basically been my dream to build a den.

So, who's up for a bit of hard work as well?

-ALL:

-Me.

-Are you sure?

-Yeah!

I'm excited about when we make the den.

It'll be fun to build it with all our mates.

There's very few places that children who have got very

complex health care needs in wheelchairs can play together

with their brothers and sisters.

So to be able to do that would be brilliant.

It's lovely to meet you, Shay.

I'm really happy.

Really happy.

It's going to give an opportunity for kids and siblings,

mums and dads to have memories,

which are more important than anything.

Our first port of call is The Dengineers Mobile HQ,

which has some mega-cool technology to get this den rolling.

And it's Ruby, Mia and Liam who are representing the hospice Dengineers.

You all use the hospice in different ways,

so you're, like, the best people to have in here to tell us

-what you're going to need from the den.

-You guys are in charge here.

We're going to take all of those ideas that you have buzzing around,

get them onto this massive screen

and we can work out how we're going to make this ginormous den.

So have a little look, see what you like.

This, so that you can chillax in there.

Wow, lovely use of "chillax".

I like the disco on there.

-That does look amazing, doesn't it? So, like a party room, maybe?

-Yeah.

I love the idea of a little sing, dance and a boogie.

Guaranteed fun.

I think this, because it represents family.

It's, like, important to have memories with your family.

Why are memories important to you?

I lost my sister a few years ago and I always think of her when

I'm at Claire House and I have fun times.

That's what it's all about, isn't it?

Remembering the really nice times you had together.

What do we think it might look like?

-Could have, like, a treehouse.

-Great stuff.

Tell us about this picture?

It's a boy and he donated his tree house so that

families could enjoy it too.

-His name's Carson.

-That's amazing.

So maybe this is something we could incorporate into the den?

Liam, what are you into that you'd quite like to see in the den?

-Cars.

-You like a bit of speed, do you, Liam?

-Yeah.

How could we incorporate speed or something into the den?

-Oh, a zip wire!

-Oh, yeah!

We could have a zip wire through the whole den.

And it could be for disabled people as well.

-That would be so cool!

-Wow!

Dengineers Ruby, Mia and Liam

have decided on a treehouse theme for the hospice mega-den.

With areas to party, chill

and make amazing memories with their friends and family.

Oh, and they'd love an exhilarating zip line too.

But who will make our Dengineers' dreams a reality?

Meet Sege.

With over 30 years in the building biz,

he's perfect to take on our biggest den ever.

But for this beast,

Sege is going to need some help,

so he's drafted in fellow designers...

..to help out.

Now, I know all your Dengineers couldn't be here today,

but I'm going to explain the den

-to you so you can go away and tell all your friends, yeah?

-OK.

I think we should create a bit of a village that's all up in the air,

on stilts. Does that sound good?

-Yeah.

-I've designed these places where you can all go and hang out,

all your parents and your friends and your siblings

-and just have a lot of fun. Your own little wonderland.

-Yeah.

You all like to communicate in different ways, don't you?

We use sign language and use our eyes to communicate.

Well, I've got a surprise for you.

There is a special part of the den

where you can all communicate, all together.

It's just going to be fantastic, I think you're going to love it.

And how about a zip line?

-Yeah!

-And wouldn't it be good if I could get you in there

-with your chair, Liam?

-Yeah.

-I think that's very, very doable.

What do you think to the designs?

-Amazing.

-Really?

-Brilliant.

-So am I good to go, then? Is this the sign off?

-Can I get started?

-Yeah.

Fantastic! I can't wait.

Sege's plans for our biggest den ever have been given

the stamp of approval from the Dengineers.

He's designed a treehouse-inspired village, including places to

communicate, party and chill out with friends and family.

As if that wasn't huge enough,

Sege has also designed a zip line which is

accessible for every child at the hospice and a Happy Path which will

contain hundreds of happy memories sent in by CBBC viewers.

I didn't think it was going to be that good

and I'm really looking forward to building it.

This is a fantastically big den.

It's the biggest build we've ever had to attempt on The Dengineers.

It's going to mean so much to the kids,

so it's really, really important that we pull this off.

Plans signed off, the team start preparing the hospice ground

for this colossal build.

And I get together a group of Dengineers to help

with a spot of housekeeping.

Jan, Leslie, you are both wonderful, we love you very much,

but we've got a message for you.

-You ready, everybody?

-Yeah.

-Three, two, one...

Get out! Dengineers only!

You ain't got a T-shirt, so see you later.

-Bye.

-We've got to go.

-We still love you! Bye!

Bye! Bye-bye.

I'm really, really excited about it.

Although a bit nerve-racking to hand over the control.

Yeah, it's going to be amazing.

For our families, time is precious.

So having a den like this outside our hospice,

what more could you ask?

For this build, Sege is planning to raise the entire den off the ground

using 170 logs.

We've got to shift all of those logs over there.

Oh...

-Are you up for it?

-Yeah.

-Yeah!

Yeah!

These logs are needed all over the site to be put into the hundreds of

holes that have been created by the Dengineers digger.

Oh, wow.

That's a lot of log!

Yes, OK!

That's it, everyone.

I do this sort of stuff all the time.

-No, you don't.

-Yeah, you can tell you don't.

If you placed all 170 logs on top of each other,

they'd be roughly the same height as three Big Bens.

It's weird, cos I'm in the gym all the time!

Joe was terrible at lifting.

And he lies.

Said he goes to the gym, but you could tell he doesn't.

Has it got to be, like, high?

Can we just, like, do a normal one, on the floor?

No?

Whilst Joe and co take a well-earned break, the rest of the team push on

and get all of the logs set into the ground.

With the ground ready,

it's time for the rest of the Dengineers team to arrive,

and they arrive with roughly 3,000 metres of timber.

If you laid this timber on top of each other

it would be the same height as 1,687 Seges, head to toe.

This is clearly the biggest den we've ever done, it's huge.

My worry is I may have gone too big, because, when you think about

the amount of time we've got to do this in, compared to

the amount of work we've got to do, I am more than worried.

There you go. Hold that tight for me, Puds!

The Dengineers have well and truly moved in

and Sege has a task that needs some immediate attention.

One of the biggest jobs we've got to do this morning

is chainsaw all of these stumps down to a certain height.

It's very important we get them almost millimetre-perfect.

If we get the calculations wrong and cut the posts too short,

we have a problem,

which would give me so much grief, it's unreal.

Whilst Dengineer Derek gets stuck in carefully cutting down the stumps,

our Dengineers help me make some refreshments for the team.

Instead of just boring old water, how about we make some fruity water?

Yeah!

The man in charge is Sege the Ledge, what kind of fruit would he have?

Cucumber? Because he's tall and thin.

-Sege and that looks exactly the same to me.

-Yeah!

There are around 50 people working on site,

so the Dengineers carry on making lots of fruity drinks.

And I catch up with Leyton,

who has a special connection to this treehouse theme.

My little brother Carson had a treehouse.

Carson was energetic and happy and he always loved everyone.

Leyton's brother Carson was very ill and spent lots of time

receiving care at the hospice.

It was a nice place to stay.

It was comfortable for Carson.

And there was lots of different rooms

where he could play and have fun.

And when Carson got quite poorly,

what was one of the things that he really wanted?

He wanted a treehouse.

And that's exactly what you got for him, didn't you?

What was the treehouse like?

It was quite big,

and he'd play games and relax and read books.

I used to read him books.

It was special.

The time came for Carson to move to the Wirral hospice full-time

and his awesome treehouse came with him.

Carson sadly died shortly after, but his treehouse is still there

for other children to enjoy as much as he did.

They like to play and hang out with friends

and they like to just get away from everyone

if they're feeling upset or unhappy,

and that's really special.

The Dengineers' drink break has done the job and the refreshed team start

to construct the steel frames for the den's amazing zip wire.

These trees have got to be protected,

so it's really important that we're very careful with the lift.

Some of the trees in this section of the hospice come with

a tree preservation order,

and that means they can't be damaged or cut down.

Whoa, whoa, whoa, whoa, whoa!

Back out, come down.

We was a little bit too high in the canopy of the tree,

so I was worried that we were going to break a branch.

We really can't do that.

The team have to carefully move the frame away from danger...

..and eventually get it into position

without breaking any branches in the process.

Disaster averted, they start to fit the steel frames in position

while Dengineer Derek works his socks off

to finish cutting all the logs down to size.

Despite the great start, the reality of the huge scale of this build

has really hit home with Sege.

I'm really, really concerned

that I really have bitten off more than I can chew on this one.

I promised these kids that they're going to get this den

and I've got to deliver.

It's day two of our gigantic build in Liverpool

and, after a quick site inspection from Dengineers Mia and Ruby...

This is amazing.

That can be for wheelchairs as well, they can get up it.

..it's time to welcome another top designer onto site.

Hi, Olga.

-Hi, are you OK?

-Yeah, are you?

What I've done is I've called in the other designers as well

to give me a hand on this. I've got Olga doing the party zone.

She understands fun.

This is her all over.

Olga's designed the perfect party zone, where our Dengineers

can customise the whole space to celebrate any occasion they want.

Birthdays, discos,

even a VIP space to spend time with their family and friends.

They are the boss of this place.

The walls of the party zone are currently being constructed,

but things aren't moving fast enough for Sege.

We are really, really struggling at the moment.

It's looking like I might even have to get some extra help.

While Sege calls in the reinforcements,

Olga needs the Dengineers' help away from the den

with an awesome upcycle using some lollipop sticks.

I've designed a section of your party zone where you can dress up,

take pictures, have loads of fun.

-Wow.

-So what we're going to do, we're going to use these

lollipop sticks and turn them into props that you

can put in front of your face.

So today, I quite fancy having a beard and a tie.

-What do you think? Does it suit me?

-Yeah!

Dengineers George and Ava pick some fun stencils...

-Beard...

-I want to do a bowtie.

-Bowtie for you.

Beard.

..and then draw around with them on some card and cut them out.

I think the party zone is going to be so important to people because,

if something's just happened close to them,

they could just go in there,

have a good time and not be in a mood.

You all deserve it so much and you're going to have

-a lovely time there with all your friends and family.

-Yeah.

Props cut out, it's time for our Dengineers to decorate them,

and add a splash of personal style.

Shall we show it?

It's that there.

-Cool.

-Is that looking good?

-Yeah.

Would you like a tie?

There's some glasses for you.

Here we go, smile!

The extra Dengineers have arrived on site and they're getting stuck in.

And away from the den, Ruby and Mia have a surprise for designer Sege.

So we heard that you're a dancing fan. Is that right?

Yes, I am a dancing fan. Yeah, I love dancing.

Well, you're going to like this. Come in, guys!

Oh!

-Hey! Yes!

-How are you?

How are you? You don't know how much I wanted to meet... Oh!

Oh, this is my dream come true!

CBBC legend Ore Oduba won Strictly Come Dancing in 2016,

and Karen Clifton reached the final with Mark Wright in 2014,

so these guys are perfect to teach our Sege some awesome

jive kicks and flicks.

We have one, two, three, four - switch - one, two, three, four.

One, two - one, two.

One, two, three, four.

-OK.

-Go on, let's try together.

-OK.

Five, six, seven, go.

One, two, three, four.

One, two, three, four.

One, two - one, two.

One, two, three, four.

Yeah!

-That's not bad.

-That is really good!

-Very good!

I can't tell you how excited I am.

I love dancing, and if I wasn't a den builder

I would love to be a dancer.

-What about if our Dengineers got involved?

-Brilliant idea.

Five, six, seven, and...

One, two, three, four.

Switch! One, two - one, two.

Just singles! One, two, three, four.

-Wow, guys.

-Hey!

That was excellent, guys.

Sege is bossing the jive moves, but it's not me he needs to impress.

It's Ruby,

Ava,

Mia

and George.

Dancing the jive.

It's Karen and Sege.

Go! One, two, three, four, switch.

One, two, three, four.

One, two - one, two.

One, two, three, four.

Whoo!

The judges' scores are in.

Amazing.

Oh, what?! Ten!

Fabulous.

Fantastic. Thank you. Oh, that's brilliant.

It's a ten from Len.

Ten!

I didn't like it.

I LOVED it.

Ten!

What they said.

Yes!

This is my best day ever.

Dancing with Karen has been special.

Been better than Christmas as far as I'm concerned.

I thought Sege was incredible.

Here's a guy who is ready to take the Strictly ballroom dance floor.

He's on it.

I want him to be my partner.

The only way that we could reward you for your amazing performance...

-It needs a trophy, Sege.

-Oh, what?!

That is absolutely brilliant.

-That is...

-For you.

-How about that?

-Sege?

-Yes!

He is coming back, right?

Whilst Ore tries to get his trophy back,

the rest of the team pack up for the day.

So Ruby and I head off to see what everyday life is like for her

and her 15-year-old sister, Holly.

So, this is a suction machine and when Holly coughs,

we use it to clear her throat out.

But we're not allowed to get this dirty,

cos it might infect her throat and she'll have to go to hospital.

And that's just for a cough,

something that is so small for us is such a big and, you know,

dangerous part of her life.

This is a sats monitor and it checks Holly's heart and her oxygen level.

If it beeps, it means she needs to go on more oxygen.

-And you look out for that?

-Yeah.

-So, this is the tube...

-That's her oxygen lead, is it?

-..that has oxygen in...

-Right.

..so if someone steps on it, like, cuts off her oxygen.

-Right.

-So we really need to be careful of this.

Absolutely. Don't put it anywhere near me.

Just take the oxygen away and I won't break it, I promise.

Holly's condition means she can't walk, talk or eat, but that

doesn't stop her communicating with her friends and family.

-I normally stroke her hand, talk to her.

-Yeah.

And she'll communicate with her eyes.

Holly's feeling OK now.

She's kind of relaxed.

She might go to sleep.

You must be the closest sisters in the world, then.

You can communicate without even talking.

Ruby doesn't so much to help care for her sister

and I'm want to find out a bit more about this from Mum.

I don't think I've ever met anybody like Ruby.

The carer aspect of their relationship,

is that something that's just developed naturally?

That's just her as a person.

She asks to do these

highly medically skilled interventions all the time.

The beauty of it is that she doesn't see it as a responsibility,

she sees it as just being with her sister.

They are best friends.

The hospice is such a big part of your life.

Do you think having the den is going to really improve

that quality of life that Holly's got and that you have as a family?

I am always thinking that one day I'm not going to have Holly with me,

but I'm always going to have the den there and I'm going to have these

special memories that will mean more to me than anything.

I can't really put into words how amazing it's going to be

for us as a family.

-Give me a cuddle.

-Oh, come on. I know!

Our Dengineers have been working really hard

so I'm giving them a break from the build to come to

this forest in North Wales, which is home to some awesome adventures.

And first up today is the Alpine coaster,

a high-speed toboggan that runs on rails

through a super-windy woodland trail.

Is it scary?

Little bit.

And for one Dengineer, going on this ride is a big deal.

Liam, you're up first.

Are you up for it?

Yeah.

Liam's condition means he spends most of his time in a wheelchair.

And as a result, he's never been on a roller-coaster before.

Good luck, guys. See you in a bit.

Whoo!

What will it mean to Liam to be doing this?

Oh, he loves it. He loves speed.

He doesn't get opportunity to do anything like this and so,

yeah, I'm made up, we've got him in!

-Did you think you'd ever get to go on something like this?

-No.

-Oh, it's so exciting!

-Yeah, he's just like the others.

Liam and health care support worker Alex are at the top

of the 710m course.

Here we go.

Time for Liam's first-ever high-octane coaster experience.

Go, Liam!

He's going so fast!

Did you see him come down that corner?

Whoo!

Go, Liam!

I've never experienced anything like that cos it was just really fast.

Liam set the super-speedy pace and next up are his fellow Dengineers.

Go, go! Go faster!

Aargh!

I got a fly up me nose!

Finally, it's my turn to take on the Alpine coaster.

This is so much fun!

Oh, my goodness me.

Yeah!

I did it!

You all right?

Tree coaster negotiated,

I joined the other group of Dengineers

on the towering tree-top nets

which stand a whopping 18 metres above the forest floor.

Three, two, one, go!

ALL SCREAM AND WHOOP IN DELIGHT

OK, this next game is who can jump the highest?

Higher. Higher!

Wah!

Wow!

Do it again!

Go up. Yeah!

All this jumping has tired me out a treat,

so I grab a breather with our Dengineers' mums and dads to talk

about the huge role this amazing den will play in their lives.

It's not often that you get out to do stuff like this, is it?

No, very rare because, obviously, Holly's care is 24 hours a day.

The hospice is caring for Holly for us today to allow us to spend that

time with Ruby, which is invaluable.

I think it's totally understandable that Holly isn't here today,

but it's such a shame and what I'm really looking forward to

with the den is that that is going to be a place that she can access

as well as all the other kids.

When you see these children and the difficulties that they have

every day to deal with, to then go into a place and just be a child,

be with their siblings,

to have that environment that is specially built just for them,

there's going to be nowhere else like it

and we're going to have that den at our hospice, how lucky are we?

And, you know, so excited.

There's only one way to finish a brilliant day like today,

and that's with a game of Dengineers versus dads dodge ball.

Go!

Ten points if you get the dads.

Take them down!

Hang on, don't hurt the Dengineers.

We've got a den to build!

Aha!

Oh!

Do you know what? I think that what you call a den day out.

Whoo!

In Liverpool, it's the morning of build day three

and Sege has called in fellow designers Tony and Satwinder

to help with the next section of the den - the Bravo Bridge.

-Hi.

-Hello, guys. How are you?

-Very well.

Good to see you.

Tony and Satwinder are absolutely perfect for this bridge.

They're brilliant architects, so this is their thing.

Tony and Satwinder have designed a curved, semi-see-through structure

for Bravo Bridge, so the Dengineers can view the entire den

when crossing over it.

They've also used vibrant wires

to add a splash of colour to the experience.

Sege and his team have constructed the bridge,

but Tony and Satwinder need the Dengineers' help

to add a colourful wow factor.

What we're doing is we're threading these coloured cords up and down

on the bridge to give it kind of a rainbow effect.

So we have to weave it through the holes, up and down.

-So it's like sewing?

-Yeah.

This is a tricky job and the more hands on deck, the better.

And it's going to take more than a muddy hill

to stop Liam helping us out.

-Yeah!

-CHEERING

Good lad!

-Liam.

-Liam, that's it.

Nice one, mate.

We feel privileged to be involved in a project

which actually means quite a lot.

It's really special and I think the fact that it's accessible

for everyone, no matter what their abilities or disabilities,

means that everyone can have fun there.

When complete, this bridge will have seven different colours of thread

running through the sides,

giving off a magical feel when you're walking over it.

Elsewhere on the site, the team are continuing work on the zip line,

the design of which has given Sege a bit of an engineering headache.

It's very important that this zip wire is accessible to everyone

at the hospice. So we've had to create a basket-shaped cradle

so that the wheelchair can go on, and their carer.

Must give you a few engineering challenges?

This is the first time I've ever worked with a zip wire

and I've learned a lot.

Your regular zip wire has just one cable on it, doesn't it? OK.

Now let me just show you first how a zip wire on one cable works, OK?

-OK.

-So if you'd just care to take that end.

-Yeah.

-OK?

-Yeah.

Now imagine this is one person, OK?

-If I send one fella down...

-Yeah.

-That's how that works.

-That was intense.

-But watch this.

-Yeah.

-This is the cradle.

-It's the basket.

-Yes.

So keep it nice and tight, watch what happens.

-Nightmare.

-Not good.

-And do you know why that's not good?

-Why?

Because look how that is tipping.

-You see?

-It's not even, is it?

-It's not even.

So anybody in the cradle is going to fall out.

So how have you solved that problem?

On this zip line...

..we're using two, TWO cables.

I think this is one of the first times this has ever been done.

-Wow.

-Watch this.

-Yeah.

OK, so do the same again, Joe, keep it nice and tight.

-Go a bit lower.

-Like that?

-OK.

Look at that!

-How good is that?

-That's, like, the best zip line ever!

And everybody here can enjoy it.

This zip has been designed with two wires

instead of the usual one wire system.

This helps spread the weight and balance the cradle.

For an added bit of engineering wow,

there's a special pneumatic break at the end of the zip

which reacts and adjusts to whatever weight is inside the cradle,

allowing for smooth stopping, no matter how many people are in there.

Back on site, Nell and her fellow Dengineers

are helping Sege paint the party zone.

You don't need to be so gentle. You can have long brushstrokes.

Nell started coming to the hospice with her brother Sam,

who sadly died when he was two years old.

He was amazing.

Like, he was so funny.

-You clearly miss him, don't you?

-Yeah.

Well, I can tell you something, Nell,

-we're going to paint away for Sam then as well, aren't we?

-Yeah.

As day three comes to an end, everyone has put in a huge effort

and things are looking up for designer Sege.

What a day.

So much progress has been made.

All the Dengineers have been brilliant.

We're still a bit behind, but do you know what, we're catching up.

It's day four of the build and there's just two days left

until the reveal of our biggest den ever.

Today's focus is the Can-Do Cabin, a place where hospice users

and their friends and family can all hang out together.

-What do you think?

-Wow, a lot is happening.

And helping Sege with this section of the den

is fellow designer, Maral.

I am so excited to be part of such a huge build.

It is for such a good cause and the children are going to love it.

It's going to be amazing.

This awesome Can-Do Cabin has been designed to look like

a traditional fairground, complete with waltzer-style seating

and a special arts and crafts cart.

Before Maral can get to work,

the team need to find an alternative way to get

the awesome arts and crafts table into the room.

We're going to try and lift this cart

over the walls and into the den

because it's too big to go through the door.

This is a fragile piece of the den,

so the team carefully place some straps around the structure

and then it's time to get this cart airborne.

Higher, higher!

Yay!

The cart is over the walls

and now we need to get it down inside the room safely.

I hope it doesn't hit anyone on the head.

Yay!

-Whoa, whoa!

-Stop, stop!

Success.

Now that the Can-Do Cabin cart has made it safely into the den,

Maral has a cool idea for some upcycled seating to go with it.

We are going to turn this very ordinary household planter

that you plant some of your herbs and stuff like that in your home,

into a very cool seat for the den.

Maral has prepainted the garden planter, but she needs Ruby,

Nell and Liam's help to apply some masking tape to areas of the seat

that she wants to keep red.

You're doing a good job.

You got it? Perfect.

Masking complete, it's time to add some paint

to the rest of the planter to give it a traditional fairground look.

We are going to dab our sponge into the paint

and cover the areas that you see are red.

Dab it quite gently.

But this is not dabbing.

What do you mean? That is dabbing.

No, it isn't, this is dabbing.

Liam dabbed Maral!

The next time Ruby, Nell and Liam will see

their upcycled garden-planter chair, it'll have a cushion attached

to the top and will be on display in the Can-Do Cabin.

I'm really looking forward to seeing it in the den

because it's something that I made and it'll stay there forever.

Back on site, the team are cracking on with our amazing Happy Path.

Sege has designed a pathway for the den

which is made out of concrete slabs decorated with hundreds

of happy memories sent in by you lovely CBBC viewers.

And our Happy Path journey started months ago, when Loz and I

went on to Blue Peter to launch an amazing Dengineer send-in.

I've wanted to be on Blue Peter since I was, like, eight.

Well, I've wanted to be a member of a Happy Path since I was eight.

Well, that's good. I've got a Happy Path and you've got a Blue Peter.

-Everyone's winning.

-Yeah.

The stage was set, time to launch our fantastic send-in to the nation.

-It's the biggest den that we've ever done...

-Really?

-Yeah.

-Yeah.

-And we need help with it, basically.

-OK, speaking of help,

-that is where you lot at home come in.

-Yes.

You need to fill out your happy memory.

You can draw it, you can write it,

you can be quite creative, can't you?

Yeah, yeah. Loads of things. And it's everyone's chance

-to be a part of history.

-I want to be a part of it, Lauren!

So basically, get involved. Come on, no excuses. Get drawing.

We received some awesome designs from you guys at home,

along with football legend Steven Gerrard.

Designs in, the next stage of our Happy Path journey

was to visit the place where your drawings have transformed

from paper to pathway slabs.

All right, Rob, how do we get our pictures onto the stones?

What's the plan?

We're going to use this cool sandblasting cabinet

to carve the designs into the stone.

We've got to do 200 of these designs,

so we need all the help we can get.

200? Girls, are you ready to help?

-Yeah!

-We're ready to help.

The first step from paper to Happy Path slab involves

using ultraviolet light to make a stencil of the original design.

The material must be strong enough to withstand

the mighty sandblasting machine.

So this big light will shine down through the stencil, onto the blue,

and create the design for us.

So we put it underneath the lamp.

Here we go.

So, this is now exposing that blue material...

-Yeah.

-..to bright light. Basically like sunlight, this,

exposing part of it, but not all of it.

And it'll switch off in a second.

There we go.

There's Joe's design. Can you see it? It's magic, isn't it?

The design is there, it's imprinted in that material.

And in a few minutes, you guys are going to make this appear.

-That's amazing.

-Yeah.

For this magnificent magic trick,

all Rob needs is a water tap and a pressure washer.

What we do is we spray the stencil with the water

and that then dissolves the design and makes it magically appear.

Wow, it's a magical sink.

So we're just moving backwards and forwards. Oh, look!

I can see a tree.

Yes.

I see coconuts!

Look at that!

Wow!

Wow.

With Mia and Nell fully up to speed, they crack on making more stencils.

Whilst Holly and Ruby join in on the next step of the process.

So, we've got the stencil here

and we're now going to push it into the big, cool cabinet

where the sandblaster will fire grit through a nozzle

and it'll carve out the design for us.

Holly and Ruby help to make sure both the concrete slab

and the sandblasting nozzle are in the correct position.

And then it's sandblasting time.

It looks brilliant.

It really does.

It's doing the clouds on your drawing.

-SHOUTING:

-It's quiet as well.

Sandblasting complete...

There we go.

..all that's left is to paint the engraved design

and peel off the stencil.

Yes! Look at that.

OK, so I'm going to leave you to do the other 199.

-We've just got to go somewhere, OK? Bye.

-Well, I...

Back at the build, the final Happy Path slabs are being laid.

And there's a special guest here to help out -

Lindsey from Blue Peter.

You can see we've got a bit of cement on the floor there.

So then what you have to do is you have to use this trowel

to smooth everything out. It's like icing a cake, actually.

-Oh, yeah.

-And what you do, is you gently squidge it down.

Do you see that line there?

We've got to get nice and level with that line. OK?

Demo complete,

it's over to our slot to start laying some Happy Path slabs.

Hello!

Right, let's get to work. Come on, team.

-Are you meant to be leaning on that one, Joe?

-What? Oh, no.

Ava, is it time for the slab proofing?

You need to get it spread more.

-Let me try.

-OK.

-Yeah, I think Lindsey will be able to do it.

-Do you reckon?

-Yeah.

Yeah. Thank you for having faith in me.

What are you doing?

What are you doing?! Do you know what I mean?

-We're putting it down, she's lobbing it about...

-I'm so sorry.

Does that matter? Oh, look, it's coming straight off.

-Girls, are you ready for a slab, mate?

-Yeah.

-Yeah? OK.

OK.

CHANTING: Joe, Joe.

-No, no!

-No, not on the string!

Who did that one?

-Did you do that one?

-No, Sege did that one.

-Oh, yours looks better than Sege's.

-You can tell that one's mine.

Yeah, yours is well better than Sege's.

With Lindsey and the Dengineers' help,

the Happy Path is finished in no time.

I've absolutely loved being here and being a Dengineer for the day.

I think anyone who sent in a memory should be super-proud

because, looking around, all you want to do is smile.

There's happiness everywhere.

The Dengineers have worked really hard today

and as day four comes to an end, Sege has some news for them.

Can I just say what a fantastic help you've been?

We'd never have got this far without you.

I've got some fantastic surprises still to get done,

so I think it's time you guys get going.

But you are going to have a most wonderful den on the reveal day.

I'm feeling sad that I won't be able to see it.

But I love surprises.

I trust Sege because he's a good designer

and I think he'll make the den even better.

With loads still to do,

the rest of the team work late into the evening.

And I'm heading off site to see what life is like for Dengineer Liam

when he's not helping to build dens.

If you wanted to get from there to here, what do we have to do?

We have to use the hoist, up there.

It's got a remote control and you bring it over and it lifts me up.

-It's like a theme park in here, innit?

-Yeah.

Sounds complicated.

I shouldn't be in charge of something like that.

-No.

-Is your mum about?

-Yeah.

-Mum?

So, you need to grab that while I grab the hoist.

This piece of equipment is really important for Liam

and he uses it every night when he goes to bed.

-Once the sling is on...

-Yeah.

..you're going to press the blue button.

-I am colour-blind, so that's a bit...

-OK, right.

-So, the one on the left.

-Got you.

Liam, are you happy for me to give this a go?

-Erm, yeah.

-JOE LAUGHS

Liam's not sure.

Everything securely attached,

it's time for the hoist to do its work,

lifting Liam out of his wheelchair and over to the bed.

Successful.

I'm a little bit in awe of you, mate.

That's something that everybody does every day and takes for granted.

Well done, mate.

Whilst Liam gets stuck into one of his racing games,

I catch up with his mum to find out how important

this den really will be for him.

It's accessible, he'll be able to go outside.

Normally when we go the hospice,

he'll be sitting inside playing the computer games,

but now he's going to join in, cos that what he wants to do,

and go outside and play with them.

And also, it's a lasting legacy.

It's going to be there forever.

And he can say, "I'm proud cos I was part of that."

It's the final day before the reveal of our biggest den ever.

And with so much work still to do,

Sege has called in some CBBC reinforcements.

Hang on a second, where's Hacker?

Ugh, that meat-paste smoothie's gone right through me!

There's so much for you guys to do over there.

I'm just going to send you over to all different parts of the den

-and let you crack on.

-All right.

-Ben Shires?

-Greetings!

-OK, you're off to the water well, please, crack on.

-Oh, a water job.

-Off you go!

-OK, and where's Ayshah from Newsround?

-I'm here, I'm here!

Zip line duty for you.

Aw, what? That's hardly fair.

-Right, Naomi from Marrying Mum And Dad?

-Here, sir.

Great, I need your help on a surprise we've got going on,

so if you head over that way, I'll come and see you

-and let you know what it is.

-Gotcha.

-So, you guys must be CBBC HQ?

-Yes, indeed.

-Correct.

Your services are requested at Paradise Hut.

-Oh, score.

-That sounds good, doesn't it?

Hang on. Take that dog with you as well.

Oh, it was too good to be true.

-Hacker?

-Off you pop, bye.

-Bye.

We are so excited to be here today. It's brilliant.

Yeah, this is such a fantastic project,

and I'll tell you what, we are not leaving until...

..this den is done!

No, we do that at the end.

-What?

-It's just a bit weird if you do it on your own.

Where did he even come from?

The first job Sege needs help with is a spot of painting

in the Paradise Hut, and CBBC HQ are raring to go.

So, Joe, how many children are actually going to use this den?

Well, over the years, it'll be hundreds.

Not just the kids, for the families as well to come and have a bit of

-quality time together.

-Sounds amazing that, Joe.

And not one to be left out,

Hacker is on hand for a bit of verbal encouragement.

You're doing a rubbish job. Paint better!

-You're not...

-Are you serious?

You're not doing anything so you can't say anything...

Well, I'm dry-clean only, Kathy!

While CBBC HQ crack on in the Paradise Hut,

Mr Ben Shires is having a closer look

at the den's wonderful water wheel.

And he wants to pick Sege's brains about the effect

these waterworks have on the environment.

Won't you need to leave the tap running 24/7

-so it keeps on turning round?

-Ah, no, you see, Ben,

we've come up with a really cool engineering solution.

So if I take this and drop it in...

So you need to imagine that this is our water wheel in our water pit.

-I'm there.

-OK.

The pit has to have water in it to start with.

And inside is a little electrical pump, OK,

the pump sucks the water up through a hose,

up onto this part of the water wheel.

So if I just demonstrate to you what happens then,

the water starts to fill these buckets up, OK?

-Can you see the buckets in the water wheel?

-It's getting full.

-And as they fill up...

-Oh!

-..the water wheel starts to move.

-Sege! Oh, it's science, Sege.

And as it drops down, what actually happens is all the water

from the buckets drops back into the pit

and then the pump does the same job all over again.

Sucks the water in, up through the hose and back round.

So actually we're not wasting any water.

We're just constantly using the same water.

I mean, how cool of an engineering idea is that?

That is incredible.

This water wheel has been engineered to sit in a pit

which has a clever pump to send the water to the top of the wheel

for it to fall back down via the buckets.

The process repeats over and over again,

constantly recycling the water in the pit.

It's now time for a very important stage of this epic build.

-Who's ready for a kickabout?

-Yay!

Oh, I don't like running.

It's Dengineers versus CBBC crew.

This duel is bigger than any local derby, any World Cup Final.

Dengineers pride is at stake.

Dengineers!

Oh, close though. That WAS close.

Yes!

Sorry. I'm sorry. I'm sorry.

All even in the big game,

our CBBC pals head back on site to help get this awesome den finished.

Ayshah is helping Sege with some finishing touches to the zip wire.

Oh, I'm a pro. I've got it.

And Naomi is getting stuck in with the surprise Communication Pad,

which will be home to some top tech.

It's a tile with the name of an emotion on there. So, happy, sad...

And when the children come along, no matter how they're feeling,

wave their hand, it lights up and shouts out, "Happy, sad."

So even if a child can't speak,

-they can tell everyone how they're feeling?

-Exactly that.

Day five is nearly done and although the team have pulled out

all the stops to get the den finished,

the amazing sensory garden is still to be completed.

So, Sege needs all the CBBC crew to muck in

and finish laying the turf.

-Get that.

-There we go.

-That's it. That's it.

-There we go.

-Oh!

-Oh, no!

You've torn the turf!

Don't grass her up.

-THEY GROAN

-Yes! Come on. Thank you.

How many idiots does it take to lay some turf?

That many.

-Yes!

-Yes!

Yes.

-Yes!

-Whoo-hoo!

After a monumental effort from everyone on site,

our biggest den ever is complete.

Yay!

This den is superb.

I mean, there's so many rooms to go into, they're all accessible.

It's just going to be great

that all the families can share time together.

It's a huge team who've worked on this den and it shows.

Everything has been done in such great detail,

with such great love and attention.

We've really enjoyed it and the den is absolutely fantastic.

They're going to love it!

This section of the new hospice started as a blank canvas.

But after five days of incredible hard work,

Sege and his humongous team of dedicated Dengineers

have transformed it into a true treehouse-inspired village of dens

where the whole hospice can make some amazing memories.

The stage is set to reveal the biggest den

the Dengineers have ever attempted,

and over 150 guests have turned up, eager to see it.

I'm really looking forward to seeing the den because it's going to

really help the children that are coming today.

It's going to have an effect on lots of people's lives

and it's going to be really important.

These children deserve this den so much.

Time is so precious, so allowing them to have a space

where they can create amazing memories...

It's just going to mean so much to everybody.

ALL: Three, two, one!

It's not a den, it's a village!

Our hospice Dengineers dreamt of a treehouse-themed den

where they could play, relax and make amazing memories

with their friends and family.

And Sege and his team have delivered the biggest den we've ever built.

What do you guys think?

That is amazing!

I couldn't have expected anything more.

It's massive and it's so colourful and bright.

I couldn't pick a better den.

This mammoth site contains not one, but four individual dens.

It also has an awesome bridge,

a magical tunnel,

a fantastic happy path

and an amazing sensory garden.

And, on top of that, it boasts a wonderful

wheelchair-accessible zip wire.

It's like a dream come true, what you've created for us.

The hospice is going to be the best hospice in the world now.

First up for our Dengineers is to see Sege's Paradise Hut,

a place where everyone at the hospice can chill

and feel like they're on holiday.

Whoa!

Welcome, welcome.

As well as an amazing tropical look,

this chilled space has a hidden feature

essential for a holiday hang-out.

What you do is you open this

and you can even look out to the beach.

-Wow.

-How about that?

That's amazing.

My favourite part of the den is the Paradise Hut,

because it's really relaxed.

Welcome to the Paradise Hut, you guys.

It's amazing. I'm absolutely overwhelmed, to be honest.

Just cos home life can be quite stressful for our little ones, so...

-No stress in here.

-No, none at all.

When you've got a child that's sick,

it impacts on the whole family.

But to come and do something fun

makes a massive difference to all the children and the families.

Next up for the Dengineers is the fantastic

fairground-inspired Can-Do Cabin, which Maral helped to design.

Come in. Come up here.

I painted the chairs.

Me and Holly did.

I'm out of words.

In here, there is loads of arts and crafts equipment,

meaning the hospice children can do anything they like.

And when they want to chill out,

there's some waltzer-style chairs

and their upcycled fairground seats.

-Don't they look good?

-Yeah.

Just incredible. It's magical, isn't it?

It's more than we could ever have imagined.

For every child, for every age,

there's something for everybody. It is just fabulous.

The fair's quite noisy for Holly and she can't really cope

with everything that's going on, so now Holly can go to the fair.

-I'm so pleased.

-It's great!

-Thank you.

-Oh, my pleasure.

Seeing their happy faces today has just meant the world.

The fact that we could have contributed a tiny bit

to their life experience has just meant a lot to me, personally.

It's Olga's Party Zone next,

which has a stylish, retro look

and can be customised to any type of party the Dengineers desire.

Oh!

What do you think?

-It's amazing.

-This is awesome.

It's going to have lots of memories here.

Or, like, the mum and dads can come here and have, like, a night out.

-What do you think? Mum and Dad's night out?

-Sounds like a plan, yeah.

My favourite bit is the disco room. It's bright, it's cheery.

The kids are just going to have a ball in there,

as will some of the adults.

Hit the music!

I think this place is going to mean so much to the kids

and to the parents. It's going to change their lives.

It meant a lot to be part of this project.

I think it's going to stay in my memory for long.

It's time for the Dengineers to see Bravo Bridge,

designed by our awesome architects Tony and Satwinder.

-What do you think to it?

-Wow. It's amazing.

It's like a big rainbow, lots of different colours...

When you walk through

you'll get all the light shining off the different cables.

-It'll be just fantastic.

-It's amazing.

-Yeah?

-Just everything about the den's amazing.

This den will mean the world to our family because, obviously,

George suffers and before he's going to have to go to hospital,

I think he would love to come here and just enjoy himself.

Boys, as with everything you do, it's beautiful.

-Thank you.

-Yeah, no worries.

-Thanks, guys.

It feels really amazing that the bridge has gone down so well

with the children, to know that it's going to have a special place

-in the children's hearts, for us, is absolutely fantastic.

-Yeah.

It's great to be part of something that's bigger than just us.

Now it's the part of the den speedster Liam has been waiting for.

OK, strap us in.

Get ready, Liam.

The hospice's very own wheelchair-accessible zip wire.

ALL: Three, two, one, go!

I think the zip line's really fun and I'd like to go on it a lot more.

Liam wanted speed.

He asked for it and he got it.

The surprises keep on coming in the form of the Communication Pad,

a place where every child at the hospice

can communicate with one another.

-COMPUTER: Excited!

-There you are, well done.

Holly can't communicate with voice like everybody else,

so this room will be amazing.

It is just absolutely awesome.

You've created a whole new world for our children, not just a den,

a whole new world for them.

And that's there forever.

It's....

Can't put a price on that.

The den is proving a massive hit with everyone here,

and the Happy Path is drawing a big crowd,

all eager to see the happy memories sent in by the Blue Peter viewers.

Me and Holly like the Happy Path,

because she can see everyone's memories that you don't even know.

Blue Peter fans, Dengineer fans, so it's really nice.

It feels so wonderful to know that so many children are going to enjoy

so much of what I've designed.

This is the biggest and most special den I've ever done.

This den's going to change hundreds and hundreds of children

and families' lives, and the excitement that this has created,

that's not what you expect in children's hospice.

It could all very much be about death and dying

and this is going to make it about life and living.

One of the big inspirations for this den was Leyton's brother Carson

and his treehouse, and we've got one final surprise in store.

Oh!

-It's brilliant.

-Do you think he'd like it?

I think he'll love it.

Thank you.

I think that the sign at the start of the den is very special

because it's representing Carson and his treehouse

and how much fun he used to have in it.

All our Dengineers absolutely love the den

and there's one person in particular that they want to thank.

One, two, three...

ALL: Thank you!

Aw, brilliant.

Let's have it. Oh, thank you. Thank you.

How grateful am I to all the Dengineers?

They've been absolutely amazing, every single one of them.

I've never seen such a large group of people come together

in one big team. Everybody's worked so hard.

It's been so friendly. Everybody's dug in for the cause.

Couldn't have asked for any more.

It's been my pleasure. I hope you all really, really enjoy it.

And make some fantastic memories.

Group hug, look, everybody in. Everybody in! Oh!

Thank you.

It's what we asked you to do, to create something where children,

brothers and sisters and the disabled children

could play and be together. You've done it.

You know, it couldn't have been any better. It's perfect.

The experience has been absolutely amazing.

I'm so lucky to have worked with the Dengineers team.

Nell's been heartbroken, losing her brother,

but this has put a positive feel back into her,

and to see her smile has made us smile.

It means more than you guys will ever know.

The Dengineers are part of our hospice family now

and you're all welcome back here any time.

My message to the Dengineers is

thank you so much for making the hospice's dream come true.

There are hundreds of people here and they're all in total agreement

about this incredible space.

ALL: This den is done!
