Nov 2024 edit: Still the best cowork I've found in the Loop having renewed my office contract three times now. New community manager, Nadya, is fostering a real sense of community and it's been great getting to know my officemates. (Her predecessor, Carley, was also super helpful when I hosted an offsite there back in June.) Love the positive vibes.
Want to get a feel for the workspace before signing up? Schedule a tour to experience Expansive 100 S State and envision your workday in this dynamic environment. All you need to do is fill out this form, indicating your preferred date and time, and we'll be happy to host you.
Adaptability is at the core of coworking, so membership options are always designed to cater to your changing work requirements and team dynamics. Most spaces offer month-to-month memberships, enabling you to adjust your workspace to your changing needs. Whether your business is growing or downsizing – or you just want to upgrade to a more private setting – you always have the flexibility to make the changes you need.
While your membership agreement may have specific terms regarding changes, don’t hesitate to reach out to Expansive to discuss accommodating your adjustments.
For spontaneous collaboration and interaction, open desks provide an open and flexible environment. If you prefer a dedicated space with shared community elements, dedicated desks offer a great balance between personal space and interaction.
On the other hand, private offices are best suited for focused work and private interactions. They're ideal for solo workers as well as teams seeking a dedicated space, shielded from distractions.
Choosing the ideal coworking arrangement for you is about aligning your workspace with your work style, team dynamics, and project requirements.
Whether you're a day pass holder or a monthly member, you can access most amenities. Meeting rooms do require prior scheduling, and private offices are reserved for those with subscriptions. However, the lounge, kitchen, and breakout spaces are open to all. Complimentary services are also available regardless of membership tier, while ancillary services can be purchased separately or negotiated with Expansive.
Expansive 100 S State 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.
