Braintree’s Planning Board has given the green light to a sweeping overhaul of the long-vacant Armstrong flooring site, clearing the way for a seven-building, 752-unit apartment complex that developers say will completely change a stretch of Plain Street. The project, the town’s largest housing plan in years, hugs the Monatiquot River and sits less than a mile from the Braintree Red Line station. If approvals stay on track, the developer says Phase 1 could start construction before the end of 2026, with Phase 2 targeted for 2027.
As reported by The Boston Globe, the Planning Board approved the site plan for the roughly $300 million development. Developers say Phase 1 will consist of four six-story buildings totaling about 427 apartments, while Phase 2 is expected to add a four-story building with 327 units and a parking garage. The Globe also pointed out that Braintree permitted only 100 net new homes between 2015 and 2024, which puts into sharp relief just how large this proposal is for the town. Mark Baranski, a vice president at Trammell Crow, told the paper the site is “a dream” for housing and said the project will be a major asset for Braintree.
According to Hollingsworth Pond Apartments, the development will span roughly 30.5 acres at 10 Plain St. and include a range of units from studios to three-bedrooms, with about 76 income-restricted apartments, or roughly 10 percent of the total. The project description notes that the development team has filed a Notice of Project Change and is undergoing review under the Massachusetts Environmental Policy Act. Plans also call for public walking-path access to a restored Monatiquot River and on-site measures aimed at cutting vehicle trips.
Why This Project Is A Big Deal For Braintree
Statewide housing reforms under the MBTA Communities Act pushed towns like Braintree to allow denser housing near transit, and in 2023 Braintree responded by updating its zoning to create overlay districts that make projects like this by-right in certain spots. As reported by Boston.com, planners say that new zoning was the key to finally unlocking the Armstrong parcel for large-scale housing. That shift helps explain why a property that sat idle for years is suddenly gliding through approvals in a way past proposals never did.
Local Concerns: Traffic And Services
Not everyone is cheering the arrival of hundreds of new apartments. Town Councilor Joseph Reynolds warned that “Braintree needs a balancing act,” and Planning Board chair Kim Kroha urged the town to stay focused on addressing infrastructure issues such as traffic and pressures on police and fire services, according to The Boston Globe. At public meetings, residents have raised concerns about congestion, pedestrian links to South Braintree Square and the sheer scale of the new neighborhood. Supporters, meanwhile, have pointed to riverfront improvements and new tax revenue as reasons to welcome the project.
What’s Next
The developer’s site states that the team has filed required environmental notices and will move through conservation and additional permitting steps before any shovels hit the ground. Local fiscal reviews cited by regional outlets describe a peer review that estimates net annual tax benefits in the mid-six to low-seven figures, amounts that town staff and planners say could help offset some of the new service costs, according to Boston.com. Details on traffic mitigation, construction phasing and management of public spaces will be worked out through upcoming permitting and in the conditions attached to the Planning Board’s approval, and the project website confirms that MEPA review and related filings are in progress. For now, final construction timing still hinges on permitting and the developer’s pre-construction work, according to Hollingsworth Pond Apartments.
The Hollingsworth Pond proposal is poised to reshape a long-idle stretch of Braintree’s riverfront and is likely to be watched closely as a test of how effectively MBTA Communities zoning can unlock bigger housing builds in suburban towns. Officials and neighbors say the coming months of permitting, traffic studies and fine-tuning will reveal whether the promised benefits outweigh the short-term strain on local services.
