Building Supporters Owner, Master High Performance Home & Commercial Inspector, Master Passive House Builder & Architect, ConstructionMuseum.com Founder & Collector + Building Scientist and Problem Solving Specialist
Brian is the mastermind behind Building Supporters, where building science meets pure genius. In his early 30s, Brian built his own 4,478 square-foot, multi-million dollar mountain home in Lyons, Colorado. As the master builder and architect, Brian built in the most difficult building code region in the USA (Boulder County), and to the most difficult standard in the world: Passive House. (R-50 walls and R-90 roof) With ZERO mortgage, Brian performed every single trade firsthand, from excavation to drywall mudding.
Beyond building architecturally-driven dream homes, Brian's love for historical and modern building methods can be seen through his Boulder, Colorado based ConstructionMuseum.com As the first construction museum in North America, Brian's remarkable collection totals more than 200,000+ historical building artifacts and tools including: the world's first framing nailer, copper from the Statue of Liberty, and cladding from the very the top of the Empire State Building. Brian's passion for understanding how every single building component works is unmatched.

"If you are lucky enough to get Brian and his team on a day that aren't sold out, then you'll get the best inspection money can ever buy. I did, and it was worth every single penny, and not just because I saved thousands of dollars in hidden repairs... But because Brian is like a walking encyclopedia of homebuilding and construction. So smart! He was so patient and easy to understand, which helped me learn firsthand about how everything in my home worked, plus how it was maintained. His work ethic, meticulous level of detail, bright enthusiasm, and all-around love for what he does are remarkable—one of a kind. A gem! You just can't find GOOD people like this these days. I couldn't be happier!" - Client
