Sustainable Home Builders Near You in Connecticut

As green home builders in CT, our services include both custom green home construction and deep green retrofits, so whether you are looking to build a new house from the ground up or transform your existing home, we can help.

Custom Green Home Construction

Every new BPC green home is customized to meet the homeowner’s priorities and designed to exceed rigorous green building certifications and standards like ENERGY STAR, Zero Energy Ready Home, and Passive House. For example, we built an Adirondack lodge home in New Canaan that was both LEED for Homes Platinum Certified and National Green Building Standard Emerald Certified, two of the most stringent green home certifications available.

Green Retrofits

If you’re looking to improve your existing home, BPC’s eco-friendly home retrofitting services provide a path to truly healthier, more efficient living spaces. Our deep green retrofits help reduce long-term maintenance costs, lower utility bills, and enhance indoor air quality.

Certified Green Homes

Every new home we build and retrofit in Fairfield, Litchfield, and New Haven counties meets at least three green building certifications: Indoor airPLUS, Zero Energy Ready Home, and EPA ENERGY STAR. Many of our homes also achieve Net Zero Energy or Positive Energy status, meaning they generate as much (or more) clean energy as they use.
