About Parcel A2
401 Congress Street, Seaport District, Boston, MA
Plans call for an 18 story, 525,000 square foot office tower on a 1.1-acre parcel at 401 Congress Street in Boston's Seaport District.
The street-level space will consist of a “grand hall” where eateries or nonprofits could set up. (The arch-like structure will minimize the need for columns in that ground-floor area.) The second and third floors will include two civic spaces, such as modest-sized performance venues. A new public connection would be made between the elevated World Trade Center Avenue and Congress Street below. And the developers would spruce up part of the viaduct — more like a park, less like a desolate bridge.
Then there’s that “triangle” parcel, bounded by highway ramps. A single-floor building devoted to civic uses — billed as an innovation and cultural center — would go there, topped with a rooftop park and connected to the office building parcel via a pedestrian bridge. Construction could start in two years, and the building could open within four.
