Posted on January 20, 2020 by WillemSunday/ more Convention Center space Here’s a peek over the fence at the construction site for the Washington State Convention Center expansion, on the edge of Seattle downtown. The steel columns and rafters that will create the cavernous spaces for the $1.8 billion Washington State Convention Center addition are starting to rise. The extension will be called ‘The Summit’ and open in 2022 for business. It is expected to bring in some $200 million a year from out of state, and is said to already have bookings for events as far out as 2026. Here is what the completed city block on Olive Way will look like. The structure will be 6 stories tall, with retail on the ground floor, a ball room, and an exhibition hall of 150,000 sq ft. The structure was designed by LMN Architects. They did the design of the University of Washington light rail station, as well as the Museum of History and Industry in South Lake Union.
