I'd recommend a proper foundation and floor slab

What would the slab depth need to be 100mm , 200mm and would i lay it direct ot to the hardcore or would i put a membrane ?? Cheers Mike

100mm concrete
25mm blinding sand
DPM
minimum 100mm hardcore

Wall foundations down to something like 600mm or so
