A Shed Obsession - part 5 - The Shonky Shed

I then had to spend a couple of weekends with friends, already arranged, but niggling at the back of my mind was that the weather was so good for building. The final finishing; getting all the windows in, the door on, filling the gaps between frames and cladding, sealing the windows all took much longer than is expected. Getting a single piece of wood the correct shape to fit could take an hour by the time all the measuring, shaving with a wheelwright plane, and fitting was done.

Here's a view of the skylight central panel in the roof... Over the weeks into October these jobs were all done and I could down tools until my next holiday and enough time to fit the green roof. Then it was search for, plan and order the green roof for the my son's half term holiday. Typically it arrived in a storm during the school run, my son's half term being a week earlier than the local primary school's. Which meant a mad hour of shifting 7m2 of Sedum turf. That left me knackered for most of the rest of the day. The next couple of days meant laying the waterproof membrane, putting the insulation layer up, the root protection layer on and placing the turf on top. I could only manage to lift .5m by 1m sections of turf up the ladder.
Finally the facia boards were on and the gravel, for drainage, placed around the sedum turf.

I could then turn to the interior fittings - finding boards to hang the bikes off. Laying a concrete render over the floor and insulating the walls.

A Shed Obsession - part 4 - Main Build Phase

Over the next days of the plan, until the end of August, it was all the complications of putting the pallets up, preparing the main roof rafters then fixing in the cross braces and the decisions around that process, particularly using recycled wood where the rafters are not exactly the same size, some aren't exactly straight. All of this plus my learning curve as I'd never built any structure before, I've built bicycles and fixed cars and that's it.
It was days of grunt, but the weather was sunny and progress was being made. Although slower than the plan, much like the costs the time was working out to be roughly double. It was not a huge surprise, I'm an experienced estimator in my work and the old paradigm of take your initial estimate and double it is about right. Particularly when you've never done it before. Reusing the old shed wood for all the internal structures (window frames, in-filling structure that the pallets didn't fill) was satisfying but slower. Finding the wood, removing old nails and then cutting it to size made it slower.

By the end of the 5 days the posts were up, the pallets in, the walls mostly completed and the roof structure beams with bracers done. I'd sourced some plyboard for the roof cover but didn't think they'd be wide enough to cover the whole roof. A friend then suggested a roof light, to sop it being too dark... which inspired a change in the design of a middle clear section rather than a solid roof. Solving two problems at once as it also solved my concerns about the weight of the green roof in the middle of the structure. It also meant that having windows East and West facing with an additional central roof panel was letting a lot more light onto my vegetable patch.

All Druidic practice was subsumed into my shed obsession. My inner guides, accessed in meditation, helped me with such pieces of problem solving. My holiday over I then had to go back to work, but the light, warm evenings of the autumn were used to continue the build. The waterproof membrane was cut and stapled into place wrapping the building. The battens went over the membrane. Fixing the plyboard sheets for the roof was done the next weekend as well as painting them with bitumen to make it watertight.

The plastic corrugated roof went sheets down the middle, it was the first real test of the roof structure as it had to take my 80kg weight, shimmying on my belly down the flat roof to finish the bitumen painting and then fix the plastic roof sheets down. It was a great feeling to get off the roof alive and with no disasters. I was becoming convinced that I'd actually created a structure that could support a green roof.


It had all been stress and worry up until then. It was satisfying to have some proof that I could build a solid structure.
The evenings were spent cladding; measuring, sawing, fixing . My old shed fence walls provided the feather lap cladding for the rear of the building (that most wouldn't see) and then I bought cheap, sustainable pine tongue-and-groove cladding (you know from where!) for the sides and front. This is where the fence post issue really bit and the reality of how un-perpendicular the posts were. The word, shonky most probably comes from a mix of shoddy and wonky. The name for this building was being formed...

A Shed Obsession - part 3 - Prep & Go

The preparation phase went roughly to plan. The current shed was emptied and then knocked down, the groundwork phase was changed to completely dismantling the old shed with an aim to reuse as much of the wood as possible. I didn't do any groundwork due to the time it took to break the old shed down into reusable pieces of wood, plus a stack of unusable wood.
Bike riding had gone on hold for Shed building and the good weather was both a blessing, from a building perspective, as well as a curse because I couldn't ride in this beautiful weather.

The details of the plan also became refined as I decided to reuse the windows from the old shed as well as a door from the outhouse. Brighton Wood recycling was contacted and wood was chosen to be delivered alongside the pallets. We could spend a long weekend in Berkshire, whilst our son was at Reading Festival.
Already compromises were coming. The costs were increasing - £500 was plainly un-realistic for the whole shed given the time & quality. With the cladding, which had to be bought new, and purchasing a green roof, once again new, the cost was going to probably double upto £1000. However, given that this is a bespoke sized insulated outdoor space with a green roof, a grand is still cheap.

Then it was time to start. Buying the posts, the wood getting delivered and clearing a working area. The difference between planning and reality started to hit. I had 18 pallets all the standard 1m x 1.2m in size but apparently there are at least 18 ways to build a standard pallet. Which meant the bolt-them-together approach was not going to work.... this was the start of the problem solving on the build. I went for various types of metal plates to screw the pallets together which I discovered in B&Q. It was lucky one had opened just 10 minutes drive down the road. I would be there quite often during the build.

Then getting the posts up and straight was not as straight forward as my thinking suggested. Queue the first of the time & cost vs quality compromises. The posts weren't quite straight, the physical constraints of building alone drove this compromise. This was the end of Day 1. I was already a half day behind schedule.

A Shed Obsession - part 2 - The Upcycle Shed Plan - Pallet Built


The inspiration for this pallet Shed came from here 
 http://ruralroutediaries.weebly.com/pallet-shed-building.html
and started with a simple  to do list...

  • Check Friday-Ad / Gumtree / Freecycle / for Doors/Windows &
  • Get Pallets from Brighton Wood recycling = £12 delivery
  • 4 concrete in posts for ground  £40 plus concrete & sand say £50
  • 12 pallets, 6 per side wall 3m wide by 2.4m high for two rows of 3.
  • 3 pallets for back wall 2.4m wide by 1m high then use 2x4 framing lumber for rest, inc window frame.
  • 2 pallets for front wall 2m wide by 2.4m high then use 2x4 framing lumber for rest inc door frame
  • Wall Breathable Membrane 30m2:

------------------------ Main build + 1 -------------------------------------------------------------------------------
Internal Phase
-- put in bike storage, organise work space

A Shed Obsession - part 1 - Planning

So, the Blog has been quiet of late, since Lughnasadh really.  The hints were in my earlier post <here> of plans for the year.   I've had a shed obsession.  From late July through to October all of my spare energy and focus has been on this 'Shed'; however more of a man-cave than humble shed.  It needed to do 3 things:
  1. Securely store my bikes
  2. Provide enough space to work on bikes
  3. Provide a flexible space for winter turbo-training (riding a bike without going anywhere!) and as a gym
  4. Optional extra - somewhere to start growing Tomato's earlier in the season

The plans really started to take shape during August when I had to settle upon a type of build.  Obviously, coming from a Gewessi mindset, ecology had to come into the mix along with practical time and cost considerations.   A set of principles formulated themselves:
  • Use recycled wood where possible
  • Cost to be ca £500
  • Timing - allow a week for primary build phase
  • Green roof
  • Time & Cost to prioritise over Quality; the quality aim is functionality with a nod to the aesthetic

Looking at the YouGov planning reg's the eaves height needs to be no greater than 2.5 metres.

So an initial plan was drawn


Then Design Options were reviewed; from building a high quality aesthetic matching the plan with all new wood, to a fully recycled wood shed.   A combination option, the middle way,  was chosen.
