About 115 Winthrop Square
Proposed 53-story, 691-foot-tall tower that would replace a decrepit City-owned parking garage located in Winthrop Square in the heart of Downtown Boston. Across the $1.3 billion, 1.592-million-square-foot tower’s top 26 floors would be approximately 500 condominium residences, with approximately 750,000 square feet of commercial office space across 20 floors below.
The tower’s first three floors would contain a 12,000-square-foot Great Hall public space. The Great Hall would create a new connection between Winthrop Square and Federal Street, and would be lined with 31,000 square feet of restaurant and retail space as well as 21,000 square feet of shared meeting space. Underneath the tower would be five levels of parking containing 550 vehicle spaces.
As part of the proposed project, 115,000 square feet of new affordable housing would be created, most likely in Boston’s Chinatown in collaboration with the Asian Community Development Corporation. Millennium would pay the City of Boston $166 million in order to acquire and develop the garage site. Construction of the proposed tower, which would be built to LEED Platinum sustainability specifications, is expected to commence in the second quarter of 2018, with initial occupancy expected by the first quarter of 2022.
