This house occupies a corner lot designated as an infill, which in urban planning means an open space that generally can be rededicated to new construction. The two-story house with a basement is set at right angle to a stream, with adequate setbacks. These help avoid obstructing the neighbor’s views. Its north- and west-façade setbacks allow natural daylight year-round. Inside, all the floors of the house are organized around a basement garden situated so as to grow vertically through openings in the floor slabs. This design feature reimagines the use of a basement and integrates it with the rest of the house.

Garden Void House is an eye-catching building with powerful straight lines, use of honest materials such as stone and wood, and minute attention to detail.

A mass-to-void relationship promotes the interconnection among different floors, an effect also enhanced by the basement garden and natural lighting.

The garden void and other double-height spaces provide the house with visual and spatial interest, but they are mainly designed as part of the building’s energy and lighting efficiency strategy.

The days of heat-producing skylights are long past. Improvements include a high haze factor, which permits diffused lighting and offers thermal breaks to optimize energy efficiency.
