House T, designed by Hiroyuki Shinozaki Architects, is a unique two person house and office located in Tokyo, Japan. The house is only accessible by a narrow alley and is surrounded on all sides by other buildings, so space was a major challenge for this design. The interior of House T is surprisingly airy and open thanks to having only one central column supporting catwalk floors that frame the limited space instead of occupying it. Each floor can be navigated using 4.6 foot tall openings and floors are connected by a stair or ladder, one of which leads to a roof terrace.
