Global Partners currently occupies 72,000 square feet at its 800 South St., Waltham headquarters, spokesperson Reid Lamberty said.

Lab developer Alexandria Real Estate Equities dropped plans for a lab conversion in 2023 and sold the property next to the MBTA’s Riverside Green Line station for $117.5 million to the new ownership team.

Global Partners plans to build out a “world-class workspace” for its local workforce on three floors of building 3 on the West Newton campus, according to an announcement by Greatland Realty Partners. Currently headquartered at 800 South St. in Waltham, Global Partners is scheduled to relocate in late 2026.
