Seattle, WA, Pioneer Building, Coworking, Building exterior
Serene space just blocks away from Lumen Field

Built in 1892, the Pioneer Building housed mining companies during the Klondike Gold Rush and Seattle’s first speakeasy during Prohibition. The Richardsonian Romanesque-style building earned National Historic Landmark status in 1978 and borders Pioneer Square Park. A flagship property for Expansive on the West Coast, it offers six floors of stunning workspace with hardwood floors, cast iron columns, and a large center atrium lit by skylights running the length of the building.

Access: Right off US-5, walking distance from the Pier 50 ferry terminal

Was traveling through Seattle and just needed a spot to get some work done. They had a fantastic day pass available. Such a beautiful historic building, full of sun and wonderful people. Great coffee, well cared for. If I lived in the area, this would be my go to.

This is a beautiful historical building and great location, and Expansive is really settling in to operating a great coworking space.The new community manager Vickii has really been pulling out all the stops. There are a good number social events which is a great help as a CEO of a small company to have some of these that I don’t have to plan personally. And whenever there are any issues she and Brandon (sales) are on top of it.Only grip is the coffee machine is broken often. There is always a backup Keurig and plenty of coffee shops within a block but I miss grabbing a quick espresso when it’s down.

Beautiful historic building right in the heart of Pioneer SquareThe building staff is amazing! Vicki (community manager), Brandon (sales), Ivanka (matriarch / building ambassador) and Michael (facilities) are all incredible and each go well above and beyond their official roles. The support I've received is actually helping my business in a material way. They're providing so much more than just my company's basic needs as a tenant.
