Our Approach

We create and deliver cutting edge sustainable homes beyond our client’s expectations. Our architecture is inspired by subtropical passive design principles which embrace individual site orientation, maximise passive opportunities, minimise costs and uses cutting edge building techniques.

We challenge the status quo of “the project housing market”, responding to the environmental impact. Sustainable delivers truly design-led, sustainable living, and sensible city infill communities that are always committed to our belief:

“By creating better buildings, we create better people.”

Ultimately, by respecting and protecting local environments we build sustainable homes that are inspirational and timeless.

Our Custom Design Approach

Sustainable Custom Homes are a Design & Construction approach that is dedicated to Client’s individual & unrestricted requests for a fully sustainably built home.

Custom built homes are designed to respond and reflect to each individual client’s personality and deliver high environmental performance over a 25-year life cycle.

Custom Designs have been a part of our Sustainable team since our very beginning – 25 whole years. Over this time, Sustainable has been awarded with over 70 high level industry awards by our peers, locally and nationally, for our leadership in design and construction of sustainable custom built homes.

As a response to the construction industry market in 2004 Sustainable’s Recipe Housing® Approach was born. Although a story of survival, Custom Design is a part of Sustainable’s DNA. 

It is where the company built its foundations – Custom Design & Construction is what we do.” – Brett McKenzie | Sustainable Pty Ltd. CEO

Our Recipe Housing Approach

Recipe Housing® is a design and building approach by Sustainable that considers elements of the building site and building pools as “ingredients” for truly sustainable homes.

Our Recipe Housing® approach was born in 2004 after the company decided to adapt to the changing construction industry markets – a method of survival.

Just like a food recipe, Recipe Housing® adapts the ratios of site and design ‘ingredients’ to respond to each site and client requirements.

The result is individual, bespoke homes and communities that respond and reflect to their environment whilst delivering high environmental performance over a 25-year life cycle.

With over 70 Australian housing industry awards, including Australian Greensmart Energy Efficient awards and Greensmart Home of the year awards, Sustainable is recognised as a Queensland leader in affordable, environmentally friendly, and bespoke homes.

Our Retrofitting Approach

Sustainable’s Retrofitting is a design and construction approach that delivers a full audit of your existing property, providing professional advice on how to proficiently renovate to improve energy and water efficiencies and to ensure continuity between existing structure and new additions.

Most of Sustainable’s retrofit projects build around and over an existing footprint to short circuit lengthy and often very costly local authority approval processes. Sustainable offers particular interest and attention into our retrofitting journeys with our clients, as we undertake a design-lead deconstruction and recycling process in order to reduce waste.

Like our other design and construction approaches to new builds, Sustainable delivers the same high quality to your extension, retrofit or renovation.
