One Congress

Transformative Development in Downtown Boston

Once complete, One Congress will offer one million square feet of office space at Bulfinch Crossing in the heart of downtown Boston. In addition to One Congress, this transformative, 4.8-acre master development will include more than 800 residential units, for both rent and sale, extensive retail, and a vibrant new net-zero pedestrian public square.

Towering at 600 feet, the building will reconnect iconic downtown Boston neighborhoods and propel a heavily transit-served site into a 21st-century global center. Totaling 43 stories, One Congress will feature breathtaking and unparalleled 360-degree views, overlooking Boston Harbor, North End, Financial District, Back Bay, and the Charles River.

One Congress will sit above 8,700 square feet of retail, two on-site T stations, a parking garage, bike-share service, electric car charging stations, and will be walking distance to two commuter rail hubs. Planned amenities include an activated triple-height lobby with a coffee and wine bar, as well as Boston’s first full-floor amenity center, including a conference and event facility, exclusive in-building dining options, a state-of-the-art fitness center, a sophisticated living room and library, and an expansive, landscaped outdoor terrace.
