The Edge at Lake Union

630 Westlake Ave N, Seattle, WA 98109

At the northern edge of South Lake Union’s innovation corridor, The Edge at Lake Union stands as a landmark of design and place—a 336,000 square foot, full block development surrounded by recreation, walkability, and world-class amenities. With features that echo the movement of water and the passage of time, The Edge delivers the flexibility, scale, and sustainability that today’s leading office and life science companies demand.

Mere steps from Lake Union Park with seamless connectivity to I-5, SR-99, and the South Lake Union Streetcar, this location places tenants at the heart of Seattle’s most dynamic and accessible neighborhood. The Edge features expansive floor plates, generous terraces, and ground-floor retail that extend the energy of Lake Union Park into a lively pedestrian realm.

Designed to inspire productivity and connection, The Edge represents the culmination of Vulcan’s two-decade transformation of the South Lake Union waterfront—and a new benchmark for what’s next.
