The long-awaited Winthrop Center at 115 Winthrop Square in Boston's burgeoning Financial District has been approved by the City of Boston. In 2016, Millennium Partners, developer of the ultra-luxury Millennium Tower in Boston's Financial District, was selected by the Boston Redevelopment Authority to redevelop the Winthrop Square Garage in Boston's Downtown Crossing neighborhood. This ultra-luxury, mixed use tower will be one of the tallest residential skyscrapers in Boston and in the Northeast United States, rising to 691 feet, 7 feet taller than the Millennium Tower a couple of blocks away. The Winthrop Square tower will also boast a 12,750 sq ft Grand Hall with 20 foot tall glass panels consisting of office, retail and restaurant space, which will be open to the public year-round and will be open directly to the sidewalk during the warmer months. The building will also contain 500 condos and 550 garage parking spaces. The top 26 floors of the Winthrop Square Tower would house the residential component of the building. The bottom 20 floors will have approximately 750,000 square feet of commercial office space. The first three floors of the Winthrop Square Tower would be home to The Great Hall, as well as 31,000 square feet of retail/restaurant space and 21,000 square feet of shared meeting space.
