Hi Mike,
You may remember this is my workshop, it was already here when I moved into the house and has served it's purpose.
However, it's 6x3m, which leaves me with 2.8m internal working width which I find too restrictive. I'm planning to build a new workshop on the same site and utilise the current wasted space between the workshop and the boundary, something along the lines of this:
(bold number are internal measurement, others external based on 300mm wall thickness)
Now because I intend to build close to the boundary and with a pitched roof I'll need PP, but by keeping below 30m2 footprint and build with brick and block (not only for flammability, but aesthetics also) I'd hope not to involve the building inspector.
The current workshop is built off a 100mm slab, if Building Control are not going to be involved could I extend that slab and lay the walls directly off it, or would that be bad practice?
Thanks
Jon
