Modern, Urban and Distinctly Northwest Design
The design of the WSCC Addition prioritizes efficiency, connections with the surrounding neighborhoods, open and engaging public spaces, and a unique experience that embodies Seattle’s special qualities. The Addition will support all the functional needs of state-of-the-art convention space while integrating mixed-use developments to enrich the urban diversity of the site. The Addition will also be a leader in sustainability, and will seek LEED Gold certification.
Inside the Addition will be approximately 570,000 square feet of usable space, including 150,000 square feet of heavy-load exhibit space with direct drive-in access, 100,000 square feet of carpeted and acoustically treated Flex Hall, 100,000 square feet of carpeted meeting space divisible into 62 versatile meeting rooms and 60,000 square feet of carpeted ballroom space divisible into four separate ballrooms.
