Architect: Velocipede Architects

Building this Shoreline home included de-constructing the existing home (handled by the ReStore) down to its original main floor platform and retaining the existing garage framing. A 5-foot addition was framed onto the south side and the house was re-built into a highly energy- and resource-efficient healthy home. The home is 1620 sf of conditioned space and has been featured in the New York Times and the Seattle P-I for its environmental features.

Environmental Building Components

This home is intended, when completed, as a Built Green 5th Star home with energy efficiency rating exceeding the Energy Star Northwest standards.
