Domestic beauty

“The main volume presents a traditional front and is wrapped on the west and south by a deep porch,” says architect Erin Sterling Lewis. “Living and dining spaces access the porch.” A standing seam metal roof with a Kynar finish and HardiePlank Lap Siding cover the exterior of this 3,000-square-foot home.

Traditionally home to merchants and craftspeople, a machiya is a type of Japanese wooden townhouse that originated in the Heian period and developed through the Edo and Meiji periods.

The double-height living space is anchored by a wood-burning stove by Lopi in the corner. The large east-facing window on the far wall floods the room with magical morning light. All the windows and doors are by Quantum.

Soft gray concrete, a polycarbonate screen, and metal roof bedeck the simple front facade of House A. Not immediately apparent? An underground water collection tank and solar panels. "We used a really high recycled content mix for our tilt-up concrete walls, which have 65-percent slag [a byproduct of steel production] instead of high-carbon emitting Portland cement," say the architects.

The east side of the living space opens up to a spectacular double-story wall of glass framed by vertical wood mullions and horizontal aluminum H-channels. A six-foot roof overhang protects the glazing from solar gain.
