Coworking has officially hit the mainstream as flexibility becomes a necessity for today’s workforce.

This has led to a wide variety of flexible options to choose from, from female-oriented community spaces to Regus centers in airports. In fact, niche coworking operators account for 84% of the U.S. market now according to The Instant Group.

For example, medical coworking firms like Lina provide doctors with flexible medical space by the hour, day or year. The Little Wing, launched by female-focused flexible office operator The Wing, is another niche option that provides mothers with childcare services.

“As employees demand a better work-life balance, they want workspaces available closer to their homes or places where they can pop in for a few hours to get work done away from the main office and away from their homes,” said Joe Brady, CEO for the Americas at The Instant Group.

Furthermore, landlords are entering the field with their own flexible office brands. For example, Tishman Speyer launched its Studio brand, which has a footprint of 300,000 square feet across its buildings in the U.S., Germany and Brazil.

Solidifying its position as a mainstay workplace solution are the amount of large corporations who are flocking to flexible offices. Coworking spaces offer these big companies an opportunity to cut costs, as well as thrive in a space where they enjoy flexibility and a sense of community.
