If I buy a two-storey stone house which needs the wooden floors, staircase, upstairs floors/joists all removed (so basically left with four external walls, internal stone walls, and a roof), would an architect be required in order to replace all floor joists and wooden floors (upstairs & down), and replace staircase?
Or could you I to the builders I want everything stripped out, but simply rebuilt in the same current layout with new materials? Or would architect plans be required?
