Capitol Core on Boylston Street in the heart of Capitol Hill is a six-story apartment building for Seattle’s sustainably-minded urban professionals. Situated on a 2,700 sf urban infill lot, the project maximizes its location with a unique linear design that created 17 homes, enabling residents to live in the heart of the city.  Built Green 4-Star certified, Capitol Core was constructed using high-performance building practices and durable materials drawn from the Passive House standard of building – toxin and allergen-free interior finishes, added insulation, extra-large windows to welcome natural daylight, and state-of-the-art, energy-efficient mechanical systems. The result offers occupants continuous fresh indoor air and a healthier, more comfortable environment with less drafts and better indoor air quality.
