Hi - looking to convert 3/4 of an integral garage, leaving the roller shutter door in place to form a small front storage / workspace on the front of a new bedroom.
Much rather do it myself and in a way that could be reversible later on and am fine with general construction / timber-work etc but struggling to find :
1. Required spec of the partition wall - ie can it be just stud partition, obviously insulated and vapour proof if need be, but can it just rest on the existing floor slab (with DPC) or maybe have a couple of courses of bricks as a base? - provided no foundations involved.
2. Best floor method - to come up 250mm to match internal house. Total 3.16m span. Prefer suspended timber floor but I'm reading a possible need for 150mm gap beneath timbers - which looks to mean only approx 80mm floor joists - which according to online span calcs is not enough even if intermediate supports - so maybe insulation and screed is only way but thats not very reversible.
Will engage with building control prob via Building Notice etc, but would really like a head start first so any advice or pointers to other online resources appreciated - most of what I've found is not relevant to part conversion.
External walls are already full brick/block cavity and insulated, roof already insulated and existing side window in place which will be upgraded so a fair amount already covered.
