This high-performance home in Columbia City, Washington is a perfect example of sustainable design. It features responsibly-harvested and recycled materials, solar power on the roof and a well-insulated, air-tight envelope – all surrounded by native plants in the garden. The Genesee Park residence, designed by First Lamp Architecture and built by Seattle-based contractor Dwell Development, is net zero energy and achieved 5-Star Built Green certification.

The architects layered materials to create a dynamic exterior. Concrete, oak, metal and fiber cement are combined with an array of reclaimed, locally sourced and recycled materials. A large rooftop solar array, airtight envelope, energy-efficient windows and thick, well-insulated walls all contribute to the high performance of the building.
