Construction of a subterranean garage and tunnel to a stair and elevator below the 3 story residence above. This presented the challenge of mitigating potential construction impacts to surrounding fine homes while employing a deep shored excavation and heavy structural construction techniques on the home's typically sized city lot.

The subterranean spaces and the windy exposure of the residential spaces required installation of a complex waterproofing system throughout the building envelope, above and below grade.

The property is designated by Seattle as an 'Environmentally Critical Area (ECA)' requiring additional regulation of the construction process, especially during the rainy fall and winter months when the site was undergoing subterranean, heavy structural, below-grade waterproofing and utilities construction.

Being a good neighbor in this fine neighborhood was critical to the Owner and to KJ. The project teams' success has been echoed in the compliments of the neighbors.
