Summit 3 Office Tower

Bellevue, Washington

Project Size:

370,000 square feet

Vision
The latest in LMN’s portfolio of 36 projects in Bellevue, Summit 3 adds a third tower to the Summit Ridge complex and fulfills the vision of the master plan first developed by LMN in 1999. Summit 3’s revised steel structure adds two additional floors on the existing constructed foundation, maximizing the potential development envelope of the site. With open floor plans, floor to ceiling glass and highly efficient systems, this new tower is designed to meet the evolving expectations of technology sector tenants.

Site and Program
The 17-story, 370,000 square foot Summit 3 tower brings additional rentable space to the corner of 108th Avenue NE and NE 4th Street, and will be built on top of an existing 7-story, below grade parking garage. High ceilings, flexible tenant floors, and additional elevators and restrooms support high occupant density, while ground floor gathering and alternative work spaces provide flexibility and enhanced collaboration. The integration of highly efficient systems allows for 70-percent vision glass to provide natural daylight to interior spaces and promote occupant well-being. The project is pre-certified LEED v4 Gold, and has been certified as Designed to Earn the ENERGY STAR.

Design
Composed of two superimposed, shifted rectangles, the building’s form responds to the architectural language of its surroundings. The main rectangle, facing east, mirrors the square-paneled rhythm of the existing Summit Ridge buildings. The other projecting, overlapping rectangle reflects the glassy, horizontal façade of the Expedia Tower 333, directly to the west, completed by LMN in 2008. Summit 3’s massing effectively mediates between these two influences, both in terms of scale and the character of its surrounding neighborhood.

Offering flexibility and adaptability for tenants in fast-paced digital industries, Summit 3 creates an attractive, comfortable and efficient environment for those who will spend most of each day there. High-performance integrated systems allow for the incorporation of floor to ceiling glass on all levels while meeting Bellevue’s aggressive energy code and the client’s sustainability goals. Extending beyond the tenant floors, the building’s street-level amenities combine meeting, lounge, lobby and retail spaces to create a central gathering area with a marble-framed fireplace. The aluminum-clad elevator core on the first and second floors provides an interesting, uniquely modern textural detail. An expanded exterior plaza features new catenary lighting, retail spill-out space and seating areas, as well as planned public art. A covered walkway completes the master plan’s internal circulation and connects to Summit II’s ground floor amenity spaces.
