Lifetime Passion for Sustainability in House Design and Construct

Sustainable was launched in April 1994 by owner Brett McKenzie.  Brett’s vision is design and build sustainable homes that complement the client’s site and work in harmony with the environment.

Brett and his team at Sustainable offer what few firms in the housing industry do by providing clients with an invaluable complete solution of sustainable design, construction, landscaping and project management. This provides their valuable clients with security and peace-of-mind during the ‘design and build’ process knowing when they make the decision to build a new home or retrofit their existing house, that Sustainable will deliver right from the initial concept design through to construction completion.
