Sure, there's a lot of prefab housing on display at MoMA right now, but have you seen any of the modular structures inhabited in New York? Design*Sponge points out a Kithaus in Williamsburg, whose "location required each module to be carried, by hand, through a 3 story brick rowhouse. The builders then added custom decks and wedged it in between warehouses and light industrial buildings to create this compact urban oasis." Prepare to be jealous as you feast your eyes upon the results. If you want one of your own, a basic kit runs around $40K. [via Brownstoner]
