35 Stone

35 Stone is a five-story core and shell office building with roughly 113,700 SF of office, 7,500 SF of retail use and below grade parking. When completed, it will be a showcase for the 2018 version of the Seattle Living Building Pilot Program, pursuing the Place, Beauty, and Materials petals of the Living Building Challenge and adhering to ambitious energy and water reductions during occupancy. The project incorporates a robust rainwater catchment program with a 269,000 gallon cistern and a high performance envelope and mechanical system to meet the strict LBPP energy reductions. It sets a precedent for what a healthy, sustainable office building can be.

The design team was inspired by historic industrial structures and created a modern expression of these forms to honor the local tie to the timber industry and showcase the mass timber framework.

The building boasts 11 balconies, a 2,000 sf roof deck, and 135 operable windows; features that promote access to daylight and fresh air. Extensive curtainwall glass highlights the mass timber structure and provides views to the surrounding neighborhood and Lake Union beyond. Natural visual connections like these have proven to boost occupant health, mood, cognitive function, and overall performance, ultimately benefiting office tenant employees.
