5. Floor Cabinets
Same part of the apartment, different functionality: Build cabinets on top of the floor and you’ll be able to easily compartmentalize—and access—clothes and supplies.
6. Fold-Down Desk
In many small rooms, it would be crazy to consider making space for a full-size desk. But you can’t write that novel in bed (well, you could, but it sure would be nice to sit on a chair occasionally), so either slip a stool under a console table or find a fold-down desk you can affix to the wall, the way the Danish firm Norm Architects did in this spare black-and-white room.
