The Seattle 2025 Worldcon, if selected, will be held in the brand new (opening January 2023) Summit expansion to The Washington State Convention Center in the heart of downtown Seattle. The under-construction Summit is a fully accessible building, with about 150,000 square feet of exhibit space and 100,000 square feet of carpeted meeting space. The space is divisible into up to 62 meeting rooms, with extensive ballrooms and lobby space, a flex hall, and a lovely fourth-floor garden terrace. The Washington State Convention Center recently achieved GBAC STAR accreditation, which indicates that they are implementing the industry's highest standards for cleaning for COVID-19. The Convention Center will implement these practices in the new Summit building as well.
