The co-working firm will open its fourth Miami area location on December 1 at the Security Building, a historic 15-story building at 117 Northeast First Avenue. This location will have space for more than 1,200 members, 20 lounges, phone booths and event space. WeWork inked a 15-year lease for the nearly 97,000-square foot building. They already have two locations in Miami Beach and one at Brickell City Centre.
