Sorry about the delay in replying, been in hospital, thanks for all the replies. Plasterboard, Interesting, I never thought of that. I currently have a prefab concrete garage of 6x2.5m, which is structurally sound, and only leaks from the roof. My initial thoughts were to take down 4m of paneling from one side of this and building it out in timber another 2.5m to the side, then by rebuilding the side approx 4.5m, to create a (roughly) 5x4.5m square with a 2x2.5m room at the back, (basically to create an L shape building) then cover it all with a flat roof and clad it all to make it look all of the same construction.
I was going to move the workshop into the newly created building, but as woodworking is a hobby, not my job, and most of the stuff I make is for family or friends, I'm now thinking more towards keeping the shed, but moving all the tools, stains, wood etc into the small room that would be created at the back of the garage. This would free up loads of space in the shed for construction, and would also offer more security for my tools. The largest piece of furniture I have made so far is a double wardrobe. This was a struggle in the shed, but any furniture I make, I tend build into finished, manageable panels where possible, then do the final assembly in situ as I it's easier to move about. I could then turn the 5x4.5m bit of the garage into a pool room/gym.
My next questions therefore are:-
1. has anyone ever extended a concrete sectional garage with timber, or heard of anyone doing it, or is this a stupid idea?
2. the max 30m2 you can build under permitted development, is that the internal, or external measurements of the building?
