Design Studio has made good use of leftover urban voids too small for a standard house and too big to leave as waste.
Their solution was to insert a slender rectangular steel frame in a rectangular footprint with elliptical ends. Organized over three stories, the ground level features a covered exterior courtyard as a semi-public space that connects to the bedroom and with a small staircase that leads up to the second floor bathroom, further continuing along the semi-circular wall up the top level kitchen and living room. A new form of compact vertical living for a single family, the home makes efficient use of the simple structure. With subtle incisions in the partitions and roof to bring in natural light.
