I’ve had a great experience working out of Expansive Pioneer Square. What really sets this space apart is the team—they’re incredibly helpful, responsive, and genuinely invested in making sure everything runs smoothly. Any time something comes up, it’s handled quickly and professionally. The space itself is consistently clean, well-maintained, and comfortable to work in day-to-day. But more than that, there’s a real sense of community here that you don’t find in a lot of shared office environments. It doesn’t feel sterile or transactional—it actually feels like a place people enjoy being. If you’re looking for a coworking space in Seattle that combines professionalism with a welcoming, community-driven atmosphere, this is it.

It is rare to find a place that to work that invites you to feel comfortable and confident like your own home. That is Vickii and her team at Pioneer Square — WFH vibes, when you can’t WFH. I am grateful for this amazing team and Vickii’s leadership. Without it, we would have ended up in a sterile work environment. Today we had a hot chocolate station, so naturally, I made a mocha with the provided coffee!

While storage in coworking spaces is generally limited, and mostly reserved for members with dedicated desks or private offices, you should always check with the coworking operator about additional storage solutions. Fill out the form on the right side of the page to reach out to them and learn all about the available options.
Open desks may be the ideal choice if you thrive in a collaborative environment and value the opportunity to connect with fellow coworkers. Dedicated desks, on the other hand, provide a designated space with shared community amenities, catering to those who seek a balance between privacy and interaction.
For ultimate focus and private interactions, private offices are best for solo individuals and teams that seek uninterrupted productivity.
Selecting the most suitable workspace for you typically hinges on your work style and preferences, but it can also be determined by the type of work that you do, its duration, and whether you work alone or in a team.
Expansive - Pioneer Building operates during regular business hours, as indicated above. For access outside of these hours, please contact the operator directly to inquire about any available options.
Flexibility is the cornerstone of coworking, so you always have the option to adjust your workspace to match your current needs. With month-to-month memberships, you can effortlessly upgrade, downgrade, or even switch between different coworking plans.
While the standard practice is to change memberships only once the current one ends, Expansive may be able to offer additional options, so it’s best to reach out to their staff directly.
To truly understand what Expansive - Pioneer Building has to offer, we recommend scheduling a tour to get a firsthand feel of the environment and amenities. Fill out this form to let us know the date and time that works for you, and we'll be happy to show you around.
