Braintree Approves 752-Unit Apartment Development on Former Factory Site

Braintree, Massachusetts, has approved plans for a 752-unit apartment complex on a 30-acre site that formerly housed an Armstrong World Industries flooring plant. The location, off Plain Street and less than a mile from the Braintree Red Line station, includes pavement and scattered buildings.

The project will replace this underused land with seven buildings in a busy commercial district along Ivory and Pearl streets.

National developer Trammell Crow is overseeing the $300 million development. The site plan received approval from Braintree's Planning Board in March 2026. The project is expected to create a new neighborhood in the town of 39,000 residents.

Project Details and Timeline The first phase includes four six-story buildings with 427 units, with construction potentially starting before the end of 2026.

The second phase will add a four-story building with 327 units, a parking garage, and public amenities such as courtyards. Groundbreaking for the second phase is planned before the end of 2027. The development will be oriented around the Monatiquot River, which runs adjacent to the site and has undergone recent restoration.

Residents will access public walking paths along the river. One building will feature ground-floor bathrooms open to the public. Mark Baranski, vice president and development manager at Trammell Crow, stated the project leverages the site's proximity to transit and the need for housing in Eastern Massachusetts.
