The new Four Seasons Private Residences One Dalton Street, Boston will be a part of Carpenter & Company’s 61-story, $700 million tower to be built in the Back Bay on a site between the Christian Science Plaza and the Prudential Center.

The tower, designed by Henry Cobb of Pei Cobb Freed and Gary Johnson of Cambridge 7 Associates, will include a 215 room Four Seasons hotel occupying the lower 20 floors, 160 Four Seasons private residences. Cobb is one of the world’s leading architects, known locally for the John Hancock Tower, and Johnson is the architect of Carpenter’s Charles Hotel and Liberty Hotel. The tower will be the tallest residential building in New England.

In addition to the residences and hotel, the property will feature a five star restaurant and bar, a fitness center with indoor lap pool and signature spa. The residences, which will be accessed through a separate entrance lobby, have spectacular unobstructed views, and will be of a quality never before seen in a new development in Boston.

The First Church of Christ, Scientist selected Carpenter following a national competition and an extremely thorough community process, as well as years of planning and public approvals. “We worked very hard to create a process to ensure that this would lead to a wonderful addition to the community contributing to our ongoing stewardship of the Plaza for the long term,” said Robert Herlinger, Chief Architect for the Church.
