Transform the end of your garden building a summer house.

Transform the end of your garden building a summer house.

Me and my Dad Ripped down out old shed and built this!
In the process my mum took a BUNCH of photos documenting the process. Apologies in advance for the shirtless photos.
so this is what the end of our garden looked like
Satisfying rip down of the old shed. We were careful, we saved the timber and utilised it to build the shuttering for the foundations (later) I wanted to rip it down with a sledge hammer but he old man reigned me in and saved us some money.
The tree in the corner had to go, its proximity to the gravel boards of the neighbours fence made it difficult to chop it down with a chainsaw. after a variety of methods we eventually got it down.
Pulling said stubborn tree down.
We hired a breaker after realising how much concrete slab there was to break up.
Some friends helping us break up and remove the existing foundations.
Quick sketch up drawing of what i wanted the summer house to look like.
The final design with bi folding front doors. We ended up building a tool shed on the side which is not pictured here. We sent these drawings to a company who make outhouses and they custom made one to our specifications. We went for a building constructed out of "sips" panels. More on this later.
Started digging out for the kind of raft foundation that we wanted to pour.
Dad taking a quick phone call amid nocking up the boarding for the concrete pour.
We employed somebody to pour the concrete. We laid steel in the concrete in order to improve its strength. i was on holiday for this stage and the weather was pretty bad. Mum didn't make it out into the garden to take lots of photos.

Our building arrived in the back of a luton box van.

These are the SIPS panels, Sip stands for structural insulated panels. The panels are two sheets of OSB sandwiched with insulation. They slip together with a fillet of pine which is glued and nailed.

We ordered them off a company called i could not recommend them highly enough.

Its worth noting that ALL of this stuff had to go through a single door side access along with every other item used to build the summerhouse.

Dad looking majestic carrying some of the fitting fillets.
Me looking less majestic.

Note the boards, we barely damaged dads precious lawn during the whole process.

also note dads flip flops. He build pretty much the whole thing in those.

Ok so. the walls went up super quick and we failed to take photos.
The process is basically screw a baseplate around the perimeter of the foundation. Glue and nail a panel to the baseplate, install a fillet in the end of the panel. Install next panel. All panels are glued and nailed.
Here we are preparing for the first window opening beam.
the small beam being carried in for the back window. the help of friends is vital.
Installing the beam over the front opening where the doors will be. These beams are heavy! it is sandwiched either side with wood and all squeezed together with coach bolts.
The panels at the front to make the angle for the roof. You can see in this photo how the panels slot together.
We sheeted up the build every night in case of rain. The main beam that you see running back to front at the moment is just wood which we rested up there purely to support the sheet.
The next day we planned to install the main steel beam. We had plenty of friends organised coming over to give us a hand, including the bloke that we bought the building off.
Long hard day. Well earned beers.
The main beam coming in from the front garden.
Beam being hoisted into the sky. Manpower only. We used the roof panels as a makeshift platform to give us the height to work on the beam.

Don't drop it.
We actually dropped the beam across the back window and it took a big chunk out of the concrete floor.
Beam in the air. With its wooden capping to form the angle for the roof panels.
Sticking proud of the front wall to form the overhang. You can see here the style of glue we used. It expands as it dries and is sort of a mix between expanding foam and glue. Its REALLY strong and you'll see later photos of us using gloves, if it gets on your hands it will stay there, for AGES.
First roof panel going into place. The roof panels are slightly thicker than the walls in order to insulate the building a little better.
The roof panels are screwed down with 200mm screws that go all the way through the panel and into the roof beam of the side supporting wall.
This is my "oh shit i'm going to drop this and die" photo.
start of the other side
Glue. Glue and more glue.

we smashed every single nail in by hand as well.

One panel each side had to be installed from the front.
We had to extend the beams coming out of the front of the building in order to provide us with enough leverage to get the panels up in the air. You can see the extension to the beam in the bottom left hand side of this photo.

The shell of the summerhouse is complete!

The grey stuff you see stapled to the outside is permeable membrane which allows the OSB to breath while keeping it dry.

We had to baton the roof and then cover in another layer of OSB. This is in order to allow the roof panels to breath. Although the OSB is treated to protect it against moisture this was an extra step that was strongly advised by the manufacturer.
We used a rubber membrane as the roofing covering. This was after a recommendation from a friend. The manufacturer delivers one sheet big enough to cover your whole roof. The downside is its HEAVY and hard to get onto the roof. We folded it in half and rolled it up and carried it on ladders as pictured. I estimate it weighed 100kgs. (220lbs ish) Once it was on the roof we unfolded it ready for it to be stuck down with adhesive.
Probably the thing i enjoyed most about the whole build, having an awesome time laughing and joking with my old man. I think this photo captures the "wouldnt it be funny if this slid of the roof" moment, while the next one catches me in the process of trying to stop it falling off the roof.
"shit, its falling off the roof"
Here you can see how the buildings roof is finished at the side. Note the extension to the front beam is still in place. At this point i almost felt like i had lived on this roof for a good couple of days.
Dad painting on the adhesive for the roofing material. I was back at work at this point and the old man and one of his mates completed this part of the build.
We built a simple timber frame shed on the side of the summer house to keep costs down. The flooring is a interlinking plastic grid system filled with gravel. The corner posts of the shed are simply fence post holders concreted into the ground. The foundations for the side shed didn't need to be as sturdy as that of the main building.
We got the timber yard to cut us some angled wood fillets to form the drop on the "flat roof" then covered the whole shabang in OSB.
Roof complete.
We sheeted the outside of the shed in OSB and dad layed a paving slab floor, the slabs were the old ones layed at the end of the garden and make a great shed floor.
Eventually we ended up double skinning the shed.
The doors arrived. we ordered aluminium bi folds. Probably the most expensive part of the build aside from the building itself. 100% worth it. Much better than PVC.
I lost counts of how many sheets of this stuff i carried down the garden.
Doors in!
Fitting them was pretty simple. They came as a complete unit (glass out) with a baseplate. Fix the baseplate to the threshold, get it level and lined up then plonk the doors ontop of it with plenty of mastick and screw them to the surround.
The tool shed is arguably my fave bit. Between me and my old man we have A LOT of tool and having them all in one place/organized has always been impossible. Now they are and we even have a bench with a vice. Hopefully to feature on many further posts in /r/DIY
A shot of the PVC cladding we used. To save on costs we used white around the outside and the back and the grey color only at the front. we batoned the outside of the building and fitting the cladding to this, again allowing the OSB to breath.
The rear window without any cladding.

Garden tools hun near the door.
Another end of day progress shot
We used a small waterproof garage consumer unit.

I am an electrician by trade so this part was probably the easiest!

Any specific questions about the electrics feel free to ask.

The old man cutting a whole for the chimney, we installed a wood burner to heat the summer house when we want to use it in the winter.
Shelving in the shed for all sorts of miscellaneous stuff.
Mock up of the wood burner chimney from the inside.
batoning the front in preperation for the cladding.
This cable eventually has a flood light connected too it.
The rear of the building in the process of being cladded.
On of the side spots before its been wired in.
Measure thrice, cut once.
The front half cladded.
Well done for making it this far. I have over 400 images of the process and i felt like these were the best 70.

This is an image of it lit up at night the first day we felt like it was "Complete"
