Every year The American Institute of Architects selects outstanding residential designs for their Housing Awards. This year the majority of the houses in the One/Two–Family Custom Housing category featured green design and energy efficient ideas. One of the awards was given to a 3,000-square-foot San Francisco residence designed and built by Jim Zack and Lisa de Vito of Zack / de Vito Architecture.
The eco-friendly design includes a translucent staircase that creates a light shaft from the skylight to the basement, wood that was harvested sustainably, and solar panels. Most of of its frame was built off-site and then put together in its final location. This process of construction reduces waste and saves time and money.
