Design/build firm PLUMBOB LLC subdivided two vacant city lots and inserted these eight condos that blend contemporary interiors with energy-efficient, sustainable living. The two-level units have light-filled, open floor plans and private outdoor spaces in the rear and on the roof. “The condos only measure 18 feet wide, but open spaces were achieved through glass floors and changes in texture,” says Howard Steinberg, AIA. An eclectic materials list—including tigerwood, solid surface, and bamboo—also helps.

Slated for LEED Platinum approval, the project includes such green features as a sod roof, a water collection system, and solar hot water collectors. It's “got a lot going on for a simple spec townhouse project,” said a judge.
