I need to have a development planning project. We decided that we would build a hotel. Our land area is 1 hectare and we plan on building a 100x70 sq.m hotel on it. I was told that 26 sq.m is an ideal room size. So now I'm wondering, along with the hallways/corridors, storage/housekeeping room, working elevator and 2 guest elevators (which I have no idea of te sizes for each) how many rooms can I fit into each floor considering everything else?
