Located in an existing 38-story core and shell office building, a first-generation buildout was performed across 13 floors. Spanning a total of 275,000 square feet, it features an open office space plan. A design-build project for a confidential technology client, Swinerton and Interior Architects (IA) tailored the firm’s new regional headquarters specifically to the needs of their employees and business partners.

The space was designed with the intent to incorporate a true Seattle vibe combined with Pacific Northwest aesthetics. Located in downtown Seattle, employees and business partners are provided with a panoramic view of Mt. Rainier to the south, the Olympics Mountains to the west, and the Puget Sound centered in between.

The project is highlighted by the addition of new interconnecting stairs that span from floor 16 to floor 18. These stairs were cut out of the existing floorplate, which required the addition of new structural steel support. Another key aspect was the creation of a large meeting room utilized for the firm’s all-hands meetings held nationwide across all of their offices. To support the occupancy load required for these meetings, additional structural steel also needed to be added to the floorplate beneath the room.

Additional features include a custom-designed “Brew Hub” for employees to socialize over a cup of Seattle’s favorite hot beverage. Utilizing mass timber construction, it is one of the key design aspects that exemplify the incorporation of natural wood throughout each floor. The utilization of blackened steel and raw concrete is also prevalent throughout each floor, which lends the spaces with an industrial aesthetic common in the firm’s other offices.
