Brady designs and builds all season, cold weather rated sunrooms for Holden, MA homes that stand up to harsh New England conditions and are protected by a 25-year warranty.
For over 45 years, since 1979, our team has been crafting fully insulated sunrooms and home additions that are tailored to each property instead of relying on generic kits.
Our signature laminated wood beams are produced in-house from sustainably managed forests by skilled craftsmen with decades of experience.
You can choose from a variety of sunroom styles and beam options, and we will design your new space to complement your home’s architecture and how you actually live, whether you envision an attached gable sunroom connected to your home or a detached greenhouse set in your yard.
Many projects are installed in just one day, giving your Holden home a transformation you can start enjoying right away.

Most sunroom additions take weeks of on-site framing and construction. Brady-Built reduces that time by building your sunroom in our factory under controlled conditions, then delivering it ready to set in place. Once the site work is complete, we can install the sunroom in as little as one day. Exterior tie-ins and interior finishing are completed after, but the biggest time savings comes from keeping most of the build out of your yard.

Our sunrooms are engineered to stay comfortable in every season. Each room includes fully insulated walls, roofing, and safety-tempered glass that block heat in summer and retain warmth in winter. The result is a bright, energy-efficient space you can enjoy every day of the year without temperature swings or high energy bills.

Every Brady-Built sunroom is built by skilled New England craftsmen using traditional mortise and tenon joinery. This method allows us to conceal fasteners within the wood, creating a clean, refined appearance that highlights the natural beauty of the timber.
Our laminated Southern Yellow Pine frame combines strength, flexibility, and long-term stability. This exceptionally strong structural wood bends slightly under pressure instead of breaking, offering impressive tensile strength and resilience. The laminated construction prevents warping or surface checking, keeping the frame true and stable through seasonal changes in temperature and humidity.

Brady-Built sunrooms are crafted with respect for the environment at every stage of production. Our wood comes from responsibly managed forests, and our precision factory process minimizes waste by using nearly every part of each timber. Installation often uses helical screw foundations that protect your yard’s natural landscape and preserve the surrounding soil and vegetation.


Each Brady sunroom comes with a 25-year warranty covering both materials and craftsmanship. We’ve been offering sunrooms & additions in Massachusetts since 1979, and we stand behind every project.
Our warranty service is handled directly by our own team, not a third-party contractor, so support comes from the same people who built your sunroom.
“Beyond the fact their products are fantastic, this is a company that stands by you post installation. When we developed a leak 15 years after installation we simply called them and they sent a technician out to fix it with no charge. The 25 year warranty is for real. It is SO refreshing to deal with a company with traditional values that stands behind their products!”
– Lewis O.
