Property design series with architect George Clarke. George travels to Macclesfield to visit a first-time builder who hopes to transform an allotment shed into a Doctor Who-style, multi-functional play den for less than 300 pounds. George visits a spectacular live-in treehouse in Scotland. Will and George dig for iron to create a medieval style lock for their wood cabin. And George's Italian road trip takes in a holiday lodge made almost entirely from glass in the Dolomite mountains.
