Yes, just a cost issue. The park floors is a really good idea, especially for very high density city developments. I had some ideas in similar thrust to yours, I think it's worth following up on. One of the cooler things you could do is space the floor plates so that you give people berths in a building. They then install walls and possibly a subfloor and run utilities. If they want to leave the space open they can, if they want to cut it up into rooms they can.
