Hi All, I am about to purchase a church in Forest Gate, London which has planning permission to create a new first floor floor of approx 1200sqft. The building is not listed. I'm comfortable with the internal works, partitions etc but I am struggling to cost for creating the first floor structure itself, as much as the steels, joists and floorboards. The span would be approximately 8.5m wide by 13 metres long with the load going into the prexisting walls. Is there a generally accepted pricing structure for these sort of things (ie x£/sqft) or what figure might I roughly be looking at? Thanks in advance,
