two twin beds. A curtain hung from that cute heading would disguise your "bedroom" if you chose. A curtain would work above as well for either a bed or built in shelves and hanging space for your clothing; I really love the idea of deep, built-in beds
this is another idea I saw in that client's house. Useful for stuff besides babies, of course. They don't want to stay all day in those little baskets anyway. Sweet idea for baby organization in a closet. You could even use it as a changing station.
