Among the many things New York is famous for is the tiny apartments of its inhabitants. Our first apartment here was about 400 square feet and somehow the people who lived downstairs from us in an apartment with the same footprint fit two people and two pitbull-type dogs into that space. In a recently released book, Apartment Therapy's Maxwell Gillingham-Ryan reveals that he and his wife live in a 250 square foot apartment in the West Village.
Having such small apartments, city residents want to make the most of the space that they have. In designing a loft apartment for his son, architect Kyu Sung Woo came up with an interesting solution to the space problem...he fit two stories into a one-story apartment. The result is The Interlocking Puzzle Loft, a surprisingly spacious two-bedroom palace crammed into 700 square feet.
As shown and described in this article from Dwell, the key element in the loft is the half-height bedroom above the kitchen and the bedroom's walkway positioned above the short downstairs hall closet and back kitchen counter, which allows the apartment's inhabitants to stand up in the bedroom. Pretty genius idea.
