Cladding for new shed build

[Lons]

Hi Jack
I would be concerned that there is no diagonal bracing in your frames which as a retired builder, I consider to be essential unless the external cladding is rigid solid sheet material. There is nothing to keep the frames square (i.e. if you pushed the top of one side frame it will push front and back out of square and could potentially collapse as a worst scenario. Same if front or back were pushed. Shiplap cladding is too thin to give that strength.

Others might disagree but for the sake of a few lengths of timber, why risk it?

That's a fair point. Where would be the best place to put in diagonal bracing?

hi Jack

I put mine corner to corner between the uprights but I guess it depends on how you're cladding the inside and what you're doing about insulation. Mine is just a large storage shed and I have photos somewhere so will post if I can find them

Hi Jack,
I am in the process of designing a combined shed/summerhouse and am unsure of the height to make the rear and front walls.
Your proportions look pretty good, what height are they?

Jack,

Not sure I can directly answer any of your questions but i'm in a similar boat and perhaps some of my experience or thoughts can help. Currently building a 20'x10' pent shed/workshop, looks very similar to yours.

Roof: Went back an forth on this but eventually selected a EPDM solution. With a single fall pent roof it just looked the easiest, slightly more expensive than felt but easier diy install and lower maintenance. Metal/sheet roof solutions did not match the look i wanted and were looking pretty pricey, I surfed ebay/gumtree for secondhand options on this and never saw anything local (but then i am in aberdeen).

Cladding: Looked at shiplap, or T&G bogstandard shed boards all the way through to posh T&G siberian larch. I was amazed at the variation in price and at the staggering amount it was going to cost me for any of the options. In the end I've opted for sheathing the shed in 11mm OSB then cladding it in locally sourced larch boards (150mmx 20mm), I emailed about a dozen local (within 75miles) saw mills and was again amazed at the variation in price, from 88p/lnm up to £1.80/lnm.

Bog standard 16mm shiplap ebay = £10ish/m²
22mm shiplap ebay = £13ish/m²
11mm OSB @ £3.4/m² + board and batten larch cladding @ £8.8/m² = £12.5/m²

Now i have made a bunch of work for myself as I have to obs sheet then cross batten then clad but it's larch so there is no painting it etc. My main learning was to email as many local suppliers, as close to the start of the supply chain (the saw mill) as possible. I had to hire a van but i bought 500m of the stuff for 400+ quid so £40 on a van made sense.

Raw boards

I happen to have a thicknesseer and plan to plane the front face of the boards on my shed as the wife doesn't particularly like the rough boards. My shed will use a vertical board and batten style.

Fitzroy, that sounds fab.
After thinking about different materials for the roof, I have also decided on EPDM. Had a good price from Permaroof, Just thinking about the steel sheets and the condensation, probably not a good idea.

Fitted 5 diagonal braces in between the uprights, but also decided to fit osb board on the inside, should strenghen the structure.
