ACCO Engineered Systems’ operational status and COVID-19 response >

333 Dexter Street
Seattle, WA


The full-block site, at 333 Dexter Ave. N., was formerly occupied by KING 5, North, and Harrison and Thomas streets. Delivery of the Shell/Core is currently underway while Tenant Improvement work is under development.The complex will have a total of 630,000 square feet of office space under two 12-story office buildings. Most floor plates will measure about 27,000 square feet. At the podium level, on floors two through four, floor plates will be about 62,000 square feet.


The shell/core buildings were developed by Swinerton under a design-build delivery with a mechanical contractor. Kilroy selected the Distech product for this initial building in the Seattle marketplace. Apple has recently signed a long-term lease of the entire building with expectations of customization of the building based on its unique employee work environments.


Currently in validation mode of the shell/core building, Sunbelt Controls is working with a new project team for the building customization for Apple. Sunbelt Controls is working with Engineers and Apple to meet Apple’s building automation system standards and experience that it has delivered on its new main campus in Cupertino, California. Integration to VRF systems, Control of Chiller Plants and Fan Coil units and Smoke Control solutions will all be in incorporated into the Building Automation System and pre-configured for Apple’s custom integration solution for its own analytics.
