The Luck Drops’ bold design was bred from necessity. It’s located on a long and extremely narrow lot, so the architects were challenged to make the shelter feel open and airy while keeping it from becoming visually cramped. Mr.Yamashiita’s solution was to use flexible walls that provide copious amounts of daylight, framing the house like a paper lantern. The translucent walls give the entire house a warm glow . Three levels provide a sparse 60 square meters of living space — kitchen and bath below, living on the first floor and a sleeping loft above.
