Im currently waiting for planning approval to build a large timber frame workshop at the top of my drive way. I sketched the plans myself and submitted them to my planning dept. with no problems.
I am now told that i will need building regs ( i knew that) but they will want architect drawings with calculations, but what calculations will they want?
Surely the building inspector should know if i'm building it correctly without expensive architect drawings? after all, the foundations will be readymix concrete, so should comply, the timber frame will be 6 x2 inch timbers at 400mm centers, with 11mm osb board and 9 x 6 inch timber window/door lintels, surely these measurements are tried and tested without the need for calculations.
And as for the roof, it will be prefab attic trusses which WILL be supplied with loading calculations by the manufacturer.
So is it COMPULSORY to have an architect? Or will they be lenient considering i'm building a workshop/shed type of building apposed to a house to live in?
