Frank understood our vision, and made my wife and I feel confident that we could see this project through to completion. From pushing through the final details of our plans, and helping us navigate our cities bylaws, Frank and his team always ensured our project was on budget and on schedule.

They have been quick to point me in the right direction for quality finishes and products, and now at the end of our build, I can say their work and attention to detail is nothing short of impeccable. The finished house is beautiful and stuns anyone who has stopped by for a visit. The fit and finish is outstanding, and looks amazing. We are settling in to our new home and are still in awe of it all. If anyone is reading this review – look no further. These guys are the real deal, and I would happily recommend them and their work to any future clients.
