The Edge at Lake Union

Where Innovation Meets the Horizon.

At the northern boundary of South Lake Union, The Edge at Lake Union is a 336,000 square foot, full-block development surrounded by world-class amenities. Mere steps from Lake Union Park with direct access to I-5, SR-99, and the Seattle 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 lively ground-floor retail. With design features that echo the movement of water and the passage of time, this development delivers the flexibility, walkability, and scale today’s leading office and life science companies require.

Designed to encourage productivity and social interaction, 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.
