I’ve just taken on an allotment plot recently. Partly so that I could grow some rad veg to eat, but mainly, if I’m honest, so I could BUILD A SHED! 😀
I thought I’d share my progress with you shed-appreciating folks here.
I work as an instructor/technician in a College, teaching cabinetmaking and so for one, have a great workshop to use but also, a two-week window over the Easter break with no students in (except Mon, Tues, Weds last week), with holiday booked to hastily build my shed. I had to be quick!
My design is inspired by boats, by camping pods, by curvy stuff, by not wanting a flat-roofed shed, and so is based on images I have been looking at online by a bloke called Stimpson, who came up with a quick and elegant way of building shelters for boat building…
The curved ribs are formed from two sections, blocks are screwed in from both sides, thereby locking the components into a curve. Dead simple really but very effective.
So, Monday morning, the first day of half-term, I laid out some moisture-resistant mdf on the floor(which would later become my floor) and started the build.
I had done a plan of sorts on Google Sketchup. The shed had to be no more than 10×8′.
Initial layout onto 2 8×4′ panels.
Curve is laid out (2440mm radius, starting from 300mm vertical from bottom to increase headspace)
Bending rib 1 around the blocks, and making any adjustments.
A large percentage of the materials I used were effectively free thankfully, else I wouldn’t have been able to do this. We had a lot of stuff left lying outside when some contractors did a massive job, finished and cleared off, leaving it all open to the elements. I rescued it 🙂
The double skin rib with blocks between at regular intervals, and screwed in from both sides.
What I was finding when I did the ribs was that just like when you steam-bend timber, or laminate timber, you get a degree of ‘springback’. The degree to which the timber springs back is pretty hard to plan for and so because of that, I found that the ribs were often turning out a bit differently to one another…
Meh…
Cutting the tops to angled length where they would meet the ridgebeam.
Larch bent components
Next up was the base. I was originally intending to use Euro pallets for this but figured I t would be way quicker in the time I had and easier just to suck up the cost and get some treated 4×2″ treated timber. Job done.
The base. 12×8′ although the actual shed will be just 10×8′ (as per allotment regs)
Layout on floor and some of the ribs (8 in total)
12×8′ base built and up on blocks to allow the curved ribs to fit which extend down past the base level.
Now I could fit the side rib-bearers and fit the ribs each side, spacing them out evenly.
Next I fitted the ridgebeam. I was on my own building this and so to fit this massive length I had to come up with a way of supporting the ends while I screwed in another end. I ended up making trusses or brackets or ridge plates or whatever they’re called that lock the ribs together from each side but leave a gap big enough for the beam to sit into. Thsi meant I could work at one end while the other end was just supported….sort of. You can just see one on the far right rib section.
I also tried a bit of cross-bracing, which they tend to use on the polythene-skinned versions of these designs, but which of course I wouldn’t need what with screwing panels to the ribs.
With the ribs screwed to the ridgebeam, I then started my attempts at skinning the structure using (because it was free) 9mm moisture resistant mdf.
The skinning worked fairly well so I moved onto fitting a door which I’d found in a skip. Made a frame out of some old Beech window linings I found too.
With a doorframe in place, I could cut and fit the ends…
A decent shed has to have a bit of light coming in and so I had the idea of using washing machine doors. One trip the the tip later…
The front end could only house one window, but for the back I decided to go a bit Pugin and made a Gothic Trefoil out of my rescued washings machine doors… 😀
While I was there, and getting a bit carried away. I thought I’d make a nice tree for the back inside wall. My idea being that I will drill lots of holes in the top of the trunk and folks can sit there of an evening with a branch and a pen-knife and whittle a nice branch or two that we can then fit to the tree, building up a nice effect over time. The bulk of it is made from local Sycamore, which was rough shaped by bandsaw and then sculpted a bit with an abrasive disc on my angle grinder.
Because I wasn’t quite busy enough already, I made a little timelapse video of me dismantling the shed (also reversed to imply building it, but I forgot…)
Once I’d mostly made the shed. I had to deconstruct it, remove the base and take the base to site in order to lay it out and sink the trunks I’d got for the pilings into the ground. The college was closed from Good Friday, right until Thursday just gone and so I just had to leave everything but the base there, while I went away and laid the foundations.
First step was having to cut the trunks down, five of them to 3 foot. I had to use a bowsaw as I don’t have a chainsaw… 😕
I then sunk some massive deep holes in each corner and one in the middle for each log.
My arms were only just long enough to clear out the bottoms of the holes where there were lots of stones.
I then laid the base, sticking in additional supports onto paving slabs here and there abouts.
I used a bit of postcrete on the main pilings.
With the base in and some good weather, it was all systems go on the build. You can see here some supports I added to screw the sides/roof to. They are just halved so that they pull against the rib when screwed through from the outside.
The shed in its new home!
It’s fair to say that the building of this has caused a bit of a stir down the allotments. Young upstarts coming in and building these shed-palaces!…
I have had a stream of people approaching me and paying the shed compliments though so it’s been a great way to meet my fellow allotmentists..
When I came to put the roof on, I fortunately had some help from a mate.
We first completely covered each end of the shed with a load of massive screen printed promotional banners that the college had chucked out. Great material and waterproofs it well.
We then followed that with a roofing felt underlay…
And that is where I am at today…
So, I’m off down there today to fit a lock to the door as it’s an old internal door and doesn’t have a lock, and then I’m going to have an almighty sit down before I’m properly back to my normal work tomorrow for a rest!
I’ll be adding some felt in the future and also doing some stuff on the inside so will update this thread.
Hope some of you like the build.
🙂
