401 Congress

Located in the heart of the Seaport District, 401 Congress will be Boston’s premier office building. In 2018, the Massachusetts Port Authority awarded the development designation to a joint venture consisting of BGI, The Cogsville Group, Bastion Companies, and EDGE Technologies. The world-class development team was selected based on the project’s iconic design, public realm contributions, and unparalleled diversity and inclusion goals.

401 Congress incorporates an iconic and innovative design that offers highly-efficient and flexible floorplates with dramatic skyline and water views. The lower floors of the building will capitalize on the Seaport’s tradition of innovation with a design and program that combines collaborative and cultural spaces. The building also employs several design features and technology to enhance sustainability and wellness to meet the modern tenants’ needs.

The project also includes a comprehensive Diversity and Inclusion Program. As owners and developers in the project, our MWBE partners at The Cogsville Group and Bastion Companies have overseen the project’s goals for MWBE Participation throughout each phase of the project.

Design development is nearing completion and the project is expected to break ground in early 2021.
