Congress Square Commons is an affordable housing project on the former site of Belfast Public Works located at 115 Congress Street in Belfast, Maine.

The project consists of forty-eight rental apartments in five new construction buildings centered around a common green space with a natural playground that incorporates topography (e.g.
hills and tunnels), texture (e.g. a variety of surface materials such as grass, native plantings, wood chips, and a boardwalk), and natural materials (e.g. logs and tree stumps).

The units are townhouse style, with an exterior entrance and a private backyard with each building having a covered space on the side of the building for bike and/or stroller storage. A community room with a kitchenette and laundry room, and broadband infrastructure with capacity to support the provision of Telemonitoring and/or Telehealth services opens out into the common green space.

Congress Square Commons is located directly on an existing public bus route provided by Mid-Coast Public Transportation and a short distance from downtown Belfast and Jack’s Grocery.
