Once known as a high-class residential area, Motoazabu is developing into more of a modern diversified metropolitan region resultant of the economic boom. The neighborhood consists of Sky Scrapers like the famous Roppongi Hills development alongside smaller just as unique small developments. But within the chaotic big city life of this area you can still find tranquil quietness. What we aimed to do with this structure was to create something that would blend with its surroundings and maintain absolute simplicity. The true character of the building can be found on the inside. A structure consisting of 4 corner columns with a footprint of 6.8m x 7.8m comprising one room. The design concept takes in a diagonal line of 450mm in room level difference which lends itself to create 4 distinct living areas all within a single space. The 2 different elevations of the floor combined with the 2 different ceiling heights lends itself to create 4 distinct living areas all within a single space. The office and living area take up the stage with views of the city and the bedroom space surrounded by post beams provides openness and a sense of privacy to modern city life in one room.
