Real estate-services firm CBRE Group is taking control of the co-working firm Industrious, a sign of the property market’s renewed interest in shared workspace as more employees return to the office. CBRE announced Tuesday that it has agreed to purchase the 60% stake that it didn’t already own in Industrious, a deal that values the co-working company at about $800 million. Industrious has more than 200 locations in over 65 cities globally that make office space available to businesses on flexible terms.
