Upon completion, the project is expected to feature 812,000 square feet of Class A office space; 572,000 square feet of residential space including 321 luxury residential units; and a 24,000-square-foot common area featuring a fitness center, game room, coffee bar, cafe and lounge space.

“Securing the construction loan from Cale Street Investments — an unprecedented investment given the global pandemic — assures that Winthrop Center will remain on schedule for completion in 2022,” says Christopher Jeffries, founder of Millennium Partners. “From its inception, human-centric design, sustainability and flexible workspaces have formed the foundation of Winthrop Center. With innovation a core part of Boston’s DNA, the city is the perfect home for this building.”

The project was designed by Handel Architects to provide ample access to natural light and elevated indoor air quality in response to the COVID-19 pandemic. The development will seek LEED Gold certification for its residential units and LEED Platinum certification for its office space upon completion, which is slated for 2022.
