Washington State Convention Center Addition

Washington State Convention Center Addition

The new Washington State Convention Center (WSCC) Addition will be a distinctly urban convention center in the heart of Downtown Seattle. The project presents an opportunity to orient and connect visitors to the richness of Seattle’s city life and natural environment. It also offers a unique chance to heal a part of the city dominated by decades of proximity to Interstate 5. Public realm improvements will help the WSCC Addition become a new center connecting surrounding neighborhoods and a valued contribution to the daily life of Seattle.

The urban landscape of the WSCC Addition encompasses four city blocks and includes commercial, residential and retail programs along with the Convention Center facility. In addition to streets designed to improve pedestrian connections for residents and visitors, a plaza and terraces at multiple levels connect the convention program to the daily life of Seattle. These spaces seek to extend the scale and character of surrounding neighborhoods into the project and integrate the project into the city.
