One of Boston’s most highly-anticipated residential structures has been knocked down a peg. Millennium Partners, developers of Boston’s upcoming Winthrop Square Tower, have announced their intentions to lower the height of the proposed building from 775 feet to 702.

The project calls for a $1.02 billion, 55-story luxury tower situated in the bustling Financial District. The developers recently discovered that the 775 foot tall structure would have stood in the path of of one of Boston Logan Airport’s runways, thereby diverting planes to other runways and sending them over communities north and west of the city that already endure increased air traffic. In talks with the Federal Aviation Administration, Millennium Partners found that a building no larger than 702 feet above sea level would be within the boundaries and avoid hindering takeoffs. In order to comply with federal rules governing building heights near airports, the height of the tower was lowered by 75 feet.

Massport’s Logan airspace map suggests a limit of 725 feet at Winthrop Square.

The 1,100,000 to 1,500,000 square-foot mixed-use project will contain residential and commercial uses as well as a below-grade garage with 550 parking spaces. The reduced height will discard five to seven floors of proposed office space as opposed to condominiums. These residences at Winthrop Square Tower are expected to redefine luxury living in the neighborhood, as it is one of the few residential high rise buildings in its proximity. It is rare for a building of this height to be proposed in the Financial District, as most of the city’s skyscrapers are situated in the Back Bay neighborhood to avoid flight path issues with Boston Logan. Millennium and its architects are currently studying plans to see if they could add to the width of the tower to avoid greatly reducing its gross square footage. The plans for the project were already controversial, as a massive tower could potentially cast shadows on the surrounding Norman B Leventhal Park and several historic structures. Though the shorter tower will cast a shorter shadow, an upgrade in its width is not without consequences.

We can expect a new round of detailed plans to be unveiled by Millennium Partners and their architects later this year. Stay up to date as more details come to light through Bushari’s Crane Watch on
