Hey everyone,
Im starting off to design and build my own workshop/shed. Will be hoping to build it in the summer. My plan is to lay a concrete slab down possibly with rebar inforcement then lay a single course of bricks around the edge of the slab for the workshop to sit on and then have the concrete base as the floor. I will lay a dpm below the concrete base. Once stud walls are up I will cover the walls with either plywood or osb then put a breathable membrane on after that before the cladding goes on. Also I will be insulating the walls inside aswell eventually. The roof will just be standard apex boarded over then polyester type felt over the top. I will have a overhang with guttering installed eventually aswell.
My questions are as follows:
1.) The course of bricks I will lay will be the anti damp blue ones. Would it still be a good idea to lay a dpm between the brick and the soleplate of the stud wall or is this not required because os the anti damp bricks?
2.) I was thinking using 2x4 all around as I will be insulating the walls inside eventually aswell, so will need the depth for the insualtion. Is this overkill or will 3x2 be sufficiant?
3.) Im stuck on what parts to use treated timber and what parts to use non treated. Most youtube videos I watch they seem to be using untreated minus the base (but wont be having a timber base). I was thinking for the sole plate of the walls to use treated but then use untreated for the rest of the walls and the roof as once enclosed and water tight I cant see why I would need to have treated. Obviously the cladding will be treated. I just dont want to overspend on treated if I dont have to.
4.) Should I join the walls together using treated corner posts (seen this in a video on youtube which gave me the base idea) or just join them together one on one? If I use treated corner posts what size posts would you use remembering still that they will be sitting on a single course of bricks.
5.) For boarding the walls is OSB sufficiant or should I go with plywood? Also will it have to be treated or can I just use untreated as will be putting a breathable membrane on after that before the cladding goes on?
IF anyone could answer just one of these questions I would appreciate it. All of them though would be great too lol
Thanks in advance
