A house can live much larger than its square footage if it recaptures little nooks and crannies that are normally thrown away. This space, for example, is a night nook just off the owners' suite where if one of a couple is sleeping, the other can slip away to read or work without annoying their spouse. And it's all built under a stairwell, in space that's normally completely wasted. If you're over 6 feet tall, you can't even stand up where the desk is… but you don't need to, of course. And the refrigerator to the left is tucked under part of the stair that's even lower.
