Space saving items- toilet/sink combos, corner sinks/toilets, etc

Those would all be great! I especially like the gray loft bed with the shelves and drawers. It's the closest I've seen to what my brother had as a child-- only the bottom bed was smaller and the chest of drawers was on the between the bed and the ladder and on the side there was a closet. There were shelves underneath the upper bunk along side the lower bed that could work like a night stand.
