First Lamp LLC: 5-Star Single-Family

Built with a homeowner in mind, this single-family home in the Bryant neighborhood of Seattle hosts many unique features not typically seen on new construction projects.

This house was designed by First Lamp to look like alternating stacked blocks, which creates extensive overhangs. In addition to the overhangs, First Lamp added a large cantilevered roof allowing for the main entry, porch, carport, and deck to be covered while providing lots of usable space to spend time outdoors year-round. To create additional privacy for the porch area, an outdoor concrete wall was built to provide a separation between the street and living space.

The home’s uniquely designed interior highlights Shou Sugi Ban paneling surrounding the fireplace, recycled cardboard light fixtures, and a small indoor atrium. Other interior finishes include polished concrete on the main floor, bamboo flooring on the additional levels, fiberglass-clad wood-framed windows, locally-made cabinets, and recycled-content quartz countertops.

On top of the design features, this house is also built to be energy efficient. Rigid sub-slab insulation and blown-in fiberglass in the walls and roof provide a good thermal envelope, while the hybrid heat pump water heater designed for domestic water use, radiant slab, ducted and ductless mini-splits, Energy Star appliances, and LED lighting all help to keep bills small. And for fresh air, the HRV will do the trick!
