Seaport Square - Block P

400 Summer Street is a 16-story laboratory building designed by Morris Adjmi Architects of New York City. The approximately 591,000-square foot building will be home to Foundation Medicine, which will occupy approximately 561,000 square feet of laboratory and office space. The building will also host 30,000 square feet of neighborhood retail uses. The Project includes the construction of the Summer Steps, a public gathering place located between 350 and 400 Summer Street that will also provide a major new pedestrian connection from Summer Street to Congress Street at the southern gateway of Harbor Way, leading to the edge of Boston Harbor.
