Ds1's room is about 3m squared. DS2's is slightly bigger, maybe 3m by 3.5, and the twins room is the same (although eventually boytwin will share with DS2 and girltwin will have this room to herself). The smallest room is absolutely fine as a bedroom size, enough room for a single bed, chest of drawers and a bookcase. There will be a built in robe in there soon too.
we live in a teeny place- DS shares with the computer/office - he's still in a cot so it works for now, but we're going to have to think about reshuffling when he's big enough for a bed!
My boys share a room. It is big enough for a double bunk and their drawers and a book shelf and a couple of square meters on the floor. Not very large but they don't spend much time in there.
