I have a ground floor rear extension waiting for a flat roof to go on. Decided to possibly plan for future timber frame second storey or if I can add to plans now. Rear extension 7.3m long by 4.3m wide. Second storey to be same width by 3m long. SE has designed a flitched beam for where end wall would go up. If prepping for future, should I put a joist in either side,board up to the flitch beam and put a separate piece of board over flitch beam so it can come up Without needing to much restructure ?
Also would I build off the beam with upright timbers or do I screw another floor plate on to the top of it. Not sure if any of this makes sense
