Hi I'm gearing up to build a wooden shed and am stuck on a few things - hoping someone here might be able to help..?
I want to make something that will last and potentially be repurposed as a usuable (small) working space in the future. From research this feels doable for less than I'd pay for a half-decent ready-made shed online. Famous last words...
Plan is to frame in 3x2 treated with 4x4 corner posts, skin in 6mm ply then clad in feather edge. I was given some Cromar vent 3 light so figured would wrap between ply and feather edge, and on roof. Roof will be an apex with ridge beam in 4x2 and rafters in 3x2, and skinned in 12mm ply/osb. Would like metal corrugated roof if I can find a good deal - might tarp over for now.
We have a concrete slab measuring 3m wide and 2.5m deep. Has dpm (2 actually!). The builders did this for us end of summer 2022 but it's taken ages to get round to the shed. Seems ok despite being exposed to the elements for so long.
Q1. Given the slab has dpm already, do I still need bearers? If not, would it be worth either laying another membrane over the whole slab or a damp proof course/some kind of barrier tape on underside of the timber frame?
Q2. What is the best way to fix rafters to ridge beam here? And is there a trick for avoiding nails/screws that are fixing the opposing rafter?
Q3. For fixing frame to concrete slab I bought some concrete frame screws (7.5x102mm) by ForgeFix but when tested didn't get great purchase so am now leaning towards a screw and plug option that I hammer in once drilled, then screw down. If anyone has a particular recommendation I'd be really grateful.
As I said, I'm a novice - but I'm keen - any help much appreciated!!!
