Expansive Pioneer Building

Located in the iconic Pioneer Building in Seattle’s Pioneer Square neighborhood, Expansive Pioneer Building offers flexible office and coworking space within one of the city’s most historically significant properties. Built in 1892, the Richardsonian Romanesque–style building originally housed mining companies during the Klondike Gold Rush and later became home to Seattle’s first speakeasy during Prohibition. The 12-story building earned National Historic Landmark status in 1978 and sits adjacent to Pioneer Square Park, just blocks from Lumen Field and steps from Pike Place Market, the Waterfront, public transit, and downtown amenities.

A flagship Expansive location on the West Coast, the Expansive Pioneer Building features six floors of thoughtfully designed workspace highlighted by hardwood floors, cast iron columns, and cast iron columns, along with a dramatic central atrium illuminated by skylights running the length of the building. Expansive Seattle offers a range of workspace options, including private offices, team suites, shared coworking areas, and flexible desks and meeting rooms designed to support a variety of workstyles. The blend of historic architectural character and modern workspace solutions creates a productive, connected environment for today’s professionals.
