About Duncan Thompson Extensions

Our Managing Director, Chris French, is a second-generation specialist domestic builder with nearly 35 years of experience in his field and he personally oversees each and all home extensions from concept to completion.

The design team includes a carefully selected group of qualified architects, draftspeople and builders who each have extensive expertise in residential home extensions, additions and home renovations.

It is their forward thinking that has created happy home extensions and sound investments for many families in the inner, eastern, south-eastern and bayside suburbs of Melbourne.

In turn, Duncan Thompson Extensions enjoys a significant referral base; a great compliment that tells us we're doing our job right.

Duncan Thompson Extensions is registered with the HIA and our objectives are seen in our hallmark 'GreenSmart' designs; a program established by HIA to promote affordable and durable environmental solutions in residential design and construction.

We are also registered with the MBAV, which aims to raise standards within the industry and serves the public by encouraging best work practice and standards.

Our extended warranties go beyond the regulatory requirements and our professionally managed leading edge quality constructions will exceed your expectations.
