Building Green

Our Commitment to a Better Built Environment

At Top Notch Contracting, we believe every project is an opportunity to build smarter, with respect for both craftsmanship and the planet. “Building Green” isn’t just a philosophy; it’s a performance standard woven into how we plan, design, and construct. From energy modeling and airtight assemblies to waste reduction and material sourcing, we’re committed to delivering homes that look beautiful, live comfortably, and perform exceptionally for generations.

Leadership Through Community

Building green is also about connection,  sharing knowledge, shaping standards, and inspiring others. Through our partnership with BRAGB and BuildingGreen, we host annual panels and educational events at our headquarters, bringing together architects, builders, and students to discuss the future of sustainable construction.
