Spring Opening — Limited Time
Spring is the best time to build your ADU.
And right now, it's even easier to get started.
This spring, get special conditions for new projects. Spots are limited.
Why Now?
Massachusetts just made ADUs legal by-right.
In 2024, Massachusetts passed the Affordable Homes Act, giving homeowners in 177 MBTA communities the legal right to add an ADU to their property. No special permits. No town-by-town restrictions.
That means your backyard could generate $2,200–$3,500/month in rental income. Or house a family member. Or simply increase your property value by $100,000+.

The Game Changer
When the laws changed,
When the laws changed,
everything clicked.
Massachusetts has a housing crisis and for decades, the answer wasn't a better building method. It was zoning reform. No matter how fast or efficiently you could build, politics and permitting made it impossible to keep up with demand.
When the ADU laws finally changed, it removed the single biggest obstacle. Suddenly, the five years the team had spent mastering cold-formed steel, a material that's 100% recyclable, fireproof, and dramatically faster to build with, became their unfair advantage.
This isn't a side project. MassDwell is building a 20,000 sqft factory, investing in robotics, and hiring a team that shares one belief: sustainable, quality housing shouldn't be a luxury. It should be the standard.

Our Story
New company.
New company.
Thirty years in the making.
Most homeowners haven't acted, not because they don't want to, but because no one made it simple enough. That's exactly the gap MassDwell was built to fill.
The company was founded by Steve Vettori and Patricia Ferreira, entrepreneurs with decades of real estate development, tech leadership, and finance expertise across New England. Powering the build side is Carlos Ferreira, PE, a licensed structural engineer and pioneer of cold-formed steel framing in the Northeast, with over 30 years of hands-on building experience.
The team had the technology. They had the expertise. But for years, zoning and bureaucracy made it nearly impossible to deliver housing at the pace communities needed.
We spent decades learning how to build. We spent five years learning how to build smarter. Now we're building what matters.
