Square room
The classic square (or rectangle) room. They are standard that have been used almost since the beginning of structures. Now since it has been around a while, almost every possible idea has been used on it, where to put things, how to make the room completely different from ever other square room. Now I myself am bored with the 90 degree 4 cornered room. But the fact is that square rooms are cheap and practicable to build. So for now we are stuck with the square room. But making the square room not as square with things like bump out walls (walls that are set pushed out from the main wall to make a focal point). Maybe just if we make focal points like these, not with furniture, but with architecture, we may just be able to escape the square room
