Chagnon Building & Remodeling
Custom Home Design & Construction
Custom Home Construction in Western Massachusetts
Building a custom home is the biggest project most people will ever take on. At Chagnon Building & Remodeling, we've been guiding Western MA homeowners through that process since 1992 — as a true design-build contractor, meaning our in-house team handles both the design and the construction under one roof.
That distinction matters. With CBR you're not hiring an architect and then shopping for a builder. You have one team, one contract, and one point of accountability from the first design conversation to the day you get your keys.
What Makes CBR Different
We are a true design-build contractor, meaning our in-house design team and our construction crews work together under one roof. That matters because:
- You work with one team from start to finish — no handing off between a separate architect and builder
- Our designers plan with construction in mind, so what gets drawn can actually be built on budget
- Communication is seamless — your designer and your project manager are always on the same page
- You have one point of accountability throughout the entire project
We use professional design software to bring your home to life visually before a single piece of ground is broken. You'll be able to see your home, make changes, and feel confident in every decision before construction begins.
Building Performance & Healthy Homes
Gary Chagnon was one of the first builders in Western MA doing deep energy builds back in the early 1990s, long before high performance construction became a talking point in the industry.
Patrick carries that forward today with a genuine passion for building science. Air sealing, water management, thermal performance, creative details that most builders never think about — these aren't upsells at CBR, they're just how we build. If you care about a home that performs as well as it looks, you'll appreciate working with a team that actually gets excited about this stuff.
We also bring that same mindset to healthy home building — indoor air quality, ventilation, low-VOC materials, and construction details that keep moisture, pollutants, and allergens out. Most clients want a comfortable, well-built home and we deliver that as a matter of course. But if you're someone who wants to go deeper on building science and healthy home performance, Patrick loves that conversation and has the knowledge to back it up.
What to Expect
Every CBR custom home project follows a clear process:
- Initial consultation — we sit down and learn about how you live, what you need, and what you've been dreaming about
- Design phase — our team develops detailed plans and works through revisions with you until everything is right
- Permitting — we handle all necessary permits so you don't have to navigate the process yourself
- Construction — our own skilled crews build your home with the same attention to detail as if it were their own
- Client portal access — throughout construction you'll have visibility into progress, schedules, and updates at all times
Our Work Across Western MA
We build custom homes throughout Western Massachusetts including Hadley, Northampton, Amherst, Belchertown, Holyoke, and surrounding communities in the Pioneer Valley. We understand the Pioneer Valley's climate — brutal winters, hot and humid summers, and everything in between — and what it actually takes to build a high performance home in Western MA that handles all of it. Not just what the code requires, but what the region demands.
Frequently Asked Questions
What does it cost to build a custom home in Western MA?
Custom home pricing depends on too many variables — lot conditions, square footage, design complexity, materials, and more — to give a meaningful number without a conversation. We'd rather give you an honest estimate based on your actual project than a number that sets the wrong expectations. Reach out and we'll talk through what's realistic for your goals.
Do you help find land to build on?
We don't assist with land acquisition, but once you have your lot we're ready to get started. If you're still in the land search phase, lining up your builder early is a smart move — we can give you feedback on whether a lot works well for the kind of home you have in mind.
How long does it take to build a custom home?
Most custom home builds take between 10 and 16 months from design through completion, depending on size and complexity. We'll give you a realistic project timeline during the design phase — not an optimistic one.
Do you build energy efficient homes?
Yes — and it goes deeper than most builders. Gary Chagnon was one of the first builders in Western MA doing deep energy builds back in the early 1990s, long before high performance construction became a talking point in the industry. Patrick carries that forward today with a genuine passion for building science. Air sealing, water management, thermal performance, creative details that most builders never think about — these aren't upsells at CBR, they're just how we build.
Do you build healthy homes?
Yes — indoor air quality, ventilation, low-VOC materials, and construction details that keep moisture, pollutants, and allergens out are all part of how we think about building. Most clients want a comfortable, well-built home and we deliver that as a matter of course. But if you want to go deeper on healthy home performance, Patrick loves that conversation and has the knowledge to back it up.
