The five places
The five spaces a small home stores in — under (beds, benches), inside (the convertible's body, ottomans), above (high band, lofts), within walls (niches, partition depth), and the freed floor (room for one good cupboard). Four of the five are opened by the three levers, not bought.
Under, inside, above, in walls, floor
Most small-home storage is occupied, not added. Only the freed floor invites a bought piece — the rest is space Subtract, Layer and Extend already opened. You read your home for these five before you buy anything.
