Articles about our work and expertise have appeared in:

“We were surprised and delighted to find in Mike Trolle, of BPC Green Builders, a local builder who not only gave us the kind of house we wanted, but helped us figure out what that was in the first place. His ideas about what a house needs — and doesn’t need — were invaluable. He even helped us find an architect whose ideas were in sync with ours.”

Tom and Stacy, Westport, Connecticut

“We found your expertise in building science to be of great help in planning the project and in the selection of appropriate equipment and materials. BPC’s management of the subcontractors and communication with us always met our expectations. Moreover, BPC was conscientious and ethical in all aspects of the work. We would be pleased to recommend BPC without reservation.”

Christine and Monte, Bethany, Connecticut
