Frequently Asked Questions

  • 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.

  • 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, ActivSpace may be able to offer additional options, so it’s best to reach out to their staff directly.

  • Please reach out to ActivSpace for more detailed information on membership options and pricing.

  • To truly understand what 3400 Harbor Avenue SW 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.

  • 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.
