CBRE Global Investors is preparing to roll out A&B, a concept that combines coworking space with other amenities and technologies. The concept will be in 20 office buildings in major U.S. markets by the end of the year.

A&B, which derives its name from "above and beyond," will aim to offer more than just shared office space, said Robert Perry, head of the CBRE Strategic Partners U.S. fund series. It will also include an amenity package, aspects of the hospitality industry and artificial intelligence-driven services, and it will be available to everyone in the building.

"Coworking companies are tenants in our buildings that sublease space," Perry said. "Above & Beyond will be offered to tenants in our buildings simply for being tenants in our buildings."

The program focuses less on what coworking technically is and more on what is at the heart of what makes coworking successful.

"Like co-work, our concept has a physical component — the space — and an amenity component. That's what you think about when you think about WeWork, for example: cool space and interesting amenities."
