The best things about Colin and the Topnotch team are integrity, attention to detail and experience. Nothing is too difficult, they have great ideas, treat you and your home with respect and answer all questions. I won’t let anyone else touch my house. You can’t go past Topnotch! 

Margot - Thornbury

With Colin and his crew on your side you can be assured of honest advice and helpfulness at every stage.  Colin went above and beyond as we made last minute changes and requested some unorthodox designs.  Every request was met with a “Can Do!” attitude,  true professionalism, and incredible expertise.

John and Bernadette - Northcote

Colin is a man of great integrity and is passionate when it comes to his building projects. He is well versed in all aspects of building from design to sign off.

Colin is hands-on and … never cuts corners, concerned for detail to a fault. We know that whatever Colin does, it will be perfect. He listens to his clients and is happy to discuss all site moves to ensure that the client understands the process and is happy. We trust Colin completely and consider ourselves lucky to have found him.
