Created by Mizuishi Architects this house in Japan is the perfect sandwiched between a river and a street, located at a junction- hence a triangular shape with extremely acute angles. Built on 29 sq.m. this piece of art contains 2 levels, with a livingroom, master bedroom and even an attic for the kids to play in. The only plot of land you can afford that bit left over on the edge of a street? No problem! With few windows, the property’s ground floor acts as a snug hideaway and sleeping area. The second floor, meanwhile, is completely open-plan and allows for plenty of light to enter into the communal living space, which comes complete with a small loft area where the little ones can play without getting under your feet.
