Braintree Fought New Housing for a Decade. Now 752 Apartments Are Moving In — Here's What It Means for You

If you've driven past the old Armstrong flooring plant off Plain Street in Braintree lately, you've probably noticed what's been there for decades: chain-link fences, crumbling pavement, and a shuttered factory shell sitting on more than 30 acres of prime South Shore land less than a mile from the Red Line.

That's about to change in a big way.

National developer Trammell Crow has received Planning Board approval for a $300 million, seven-building, 752-unit apartment complex on the former Armstrong site — to be called Hollingsworth Pond Apartments. It's the largest housing project Braintree has seen in years, and it signals something worth paying attention to if you own a home — or are trying to buy one — anywhere on the South Shore.

How Did We Get Here?

Braintree has a well-earned reputation for resisting new housing. Between 2015 and 2024, only 100 net new homes were permitted in the entire town — one of the lowest totals among Boston's inner-ring suburbs. Anyone who followed the South Shore Plaza saga knows the dynamic well: a developer proposes apartments, residents show up with yard signs, and the project dies or gets scaled back dramatically.

That resistance isn't unique to Braintree. It's a pattern across virtually every South Shore town — and frankly, across most of Massachusetts. People choose their communities deliberately. They value the neighborhoods they bought into, and the instinct to protect that is understandable. Nobody moves to the suburbs hoping a 752-unit apartment complex shows up down the road.

But here's the other side of that coin: decades of "no" produced one of the worst housing shortages in the country. The South Shore — like most of eastern Massachusetts — simply doesn't have enough homes for the people who want to live here. Something had to give.

What changed? The MBTA Communities Act — the 2021 state law requiring communities served by the T to allow denser multifamily housing — was the turning point. Braintree passed compliant zoning in 2023, opening the Armstrong site to by-right development and removing the political risk that had made large-scale projects essentially impossible to finance. The new zoning was, in the developer's own words, "the key to unlocking the site."

It's worth zooming out for a second. New housing permits across Massachusetts as of mid-2025 were down 44% from 2021 levels — which means the pipeline of new homes coming to market is getting thinner, not thicker. Against that backdrop, a 752-unit approval isn't just local news. It's a meaningful step forward in a state that is genuinely struggling to build its way out of a housing shortage.

What's Actually Being Built?

Phase one — four six-story buildings totaling 427 units — could break ground before the end of 2026. Phase two adds a four-story building with 327 more units, a parking garage, and public amenities, with groundbreaking targeted before the end of 2027.

The project will be oriented around the Monatiquot River, which runs alongside the site and was recently restored, with public walking paths along the riverbank. Think less "suburban apartment sprawl" and more "new neighborhood anchored by green space" — a genuine revitalization of a site that has been an eyesore for nearly three decades.

Of the 752 units, 76 will be designated as affordable housing under state law — roughly 10% of the total development. That's the baseline requirement under Massachusetts zoning, and it's a meaningful number for anyone tracking affordability in a market where entry-level options have been disappearing fast.

What Does This Mean for the Braintree Market Specifically?

Here's some context that makes this development easier to put in perspective.

Braintree is already a competitive market. Homes there have been selling in under 30 days, with a median sale price that's been tracking in the $668,000–$725,000 range — up meaningfully year over year. Inventory is tight. Buyers are competing. This is a strong market, and a project of this scale has the potential to make it stronger.

Adding nearly 800 apartments brings real benefits to the town. It generates significant property tax revenue — a $300 million development makes a meaningful difference to Braintree's budget, which in turn supports town services, schools, and infrastructure. It creates a new neighborhood on a long-blighted site. And it gives renters who want to put down roots on the South Shore a quality place to land while they work toward homeownership.

There's also a broader supply dynamic at play. New rental inventory gives some would-be buyers a place to breathe while they save — which can actually reduce some of the frantic competition that's been making the ownership market so difficult for first-timers.

The Rate Lock-In Factor

One dynamic this project doesn't solve — but is worth understanding — is the rate lock-in effect. A huge number of South Shore homeowners are sitting on 2.5–3% mortgages from 2020 and 2021. They're not selling, not because they don't want to move, but because trading that rate for today's 6%-plus environment means a dramatically higher monthly payment even on a lateral move. That's one of the primary reasons inventory has stayed so thin.

New apartment supply doesn't unlock those sellers. But it does provide a pressure valve for the renters and would-be buyers who've been stuck in a holding pattern — and that's meaningful for the overall health of the market.

What Does This Signal Regionally?

The MBTA Communities Act is quietly reshaping the development landscape across eastern Massachusetts — and Braintree's relatively smooth approval of a project this size sends a clear message to developers: the legal environment has changed. Expect more proposals in more towns. Weymouth, Quincy, Randolph, and other Red Line and commuter rail communities are all operating under the same zoning framework now.

For homeowners and buyers in Hingham, Weymouth, Canton, and surrounding towns, that's worth watching. New rental supply in Braintree could draw renters away from neighboring markets — easing competition slightly. Or it could attract a wave of new residents to the area who eventually transition into homeownership in the towns around it. Both scenarios have ripple effects on pricing and inventory.

The Infrastructure Question — And Why It Matters

Optimism about this project comes with a realistic footnote: growth has to be managed well to deliver on its promise.

Plain Street and the surrounding corridor are already busy. The commercial stretch near Ivory and Pearl streets handles significant daily traffic as it is. Adding 752 apartments means adding real volume to roads that weren't designed with that scale in mind. Braintree's Planning Board has already flagged the need to manage increased demand on traffic, police, and fire services — and how the town handles that transition will matter to existing residents and newcomers alike.

This is the part of big development stories that often gets glossed over. The approval is the headline. The execution — the traffic studies, the infrastructure investment, the phased buildout — is where a project like this either fulfills its promise or creates headaches. It's worth staying engaged as this moves forward.

A Note for Homeowners Who Are on the Fence

Here's something worth saying directly: change of this magnitude affects different homeowners differently, and that's okay.

For some, this is exciting — a revitalized neighborhood, a stronger tax base, a more dynamic town. For others, the prospect of significant growth near their neighborhood raises real questions about traffic, congestion, and the pace of change. Both reactions are completely valid.

What I'd say to anyone in the second camp is this: Braintree's market is strong right now. Values are up. Inventory is still tight. If you've been thinking about making a move — whether that means upsizing, downsizing, or relocating entirely — this is actually a moment of real leverage. Selling from a position of strength, with the market working in your favor, is always better than waiting to see how things shake out.

That's not a reason to panic. It's just a reason to have the conversation sooner rather than later.

The Bottom Line

On balance, this is good news for Braintree — a blighted industrial site transformed into a new neighborhood, meaningful tax revenue coming into town, and hundreds of new housing options in a region that desperately needs them. The concerns about infrastructure and pace of change are legitimate, and the town will need to manage them thoughtfully.

But the bigger picture is clear: the South Shore is growing, the demand for housing isn't slowing down, and communities that find ways to grow smartly are going to be stronger for it in the long run.

If you own a home in or near Braintree and you're wondering what this means for your value, your neighborhood, or your timing — I'm happy to have that conversation. No pressure, no agenda. Just an honest look at where the market stands and what your options are.
