Your Assurance Testimonials

I wish Sustainable all the best! Brett and his team have been fantastic to deal with. The house achieves a level of environmental sustainability we had only dreamed about when we started this project two years ago. Brett’s experience in designing zones for large families, and our shared passion for minimal environmental impact while maximising the passive elements of the Queensland climate has resulted in the home of our dreams.

It is a great experience to work with Sustainable. Every time someone from Sustainable comes on site it is like a friend arrives. I feel as if I am part of the family and always encouraged to be part of the project, so that I understand the methodology and reasons of the design and delivery. I also appreciate the philosophy of Sustainable that involves listening to my needs, wishes and coordinates whatever is necessary.

Carolyn Murray- Retrofit client @ Karana Downs

We had a great experience working with Sustainable and could not be any happier with the results. Their aesthetic ideas were very creative and appealing, and their practical know-how and problem solving ability were invaluable when it came to the particular challenges with our site, such as access and water flow. It was obvious to me that the whole team, from Brett at the top, and all the way through, were very enthusiastic about what they were doing and saw it as much more than just a ‘job’.

The scope of the works that were completed for us included:

  • Construction of an internal courtyard;
  • Land clearing and contouring;
  • The establishment of a small water retention pond;
  • Erection of privacy screens; and
  • The reinstatement of turf on any heavily trafficked areas.

Their commitment to the project both in the conception stage and delivery were excellent, we had a strict deadline which Sustainable were able to meet, and they proved they were able to draw on enough workers to ensure that the job was done.

100% perfection! I have worked in the building industry for a very long time and I was extremely impressed with the service (they were always on time and always cleaned up afterwards), the staff and the outcome of the project on my garden. I would highly recommend them to anyone and would definitely use them again for any other projects on my property.

For decades we’d enjoyed our ‘secret spot’ – getting there by 4WD and camping under the stars. As chance would have it, we discovered a freehold block of land that had come on the market. We wasted no time and soon it was ours. Over many years after that we thought about the future, and securing an architect and builder to serve our needs in a remote location. We met with many good architects. Some were ‘out there’ and some hadn’t worked with solar or on-site sewage treatment, but ‘would like to get into it’.

The trail eventually led us to Brett McKenzie and the Sustainable team. We were impressed by their organisation and ability to competently design, build and manage the project throughout. They analysed our needs, considered the site and its best assets; then used their skills and knowledge to efficiently create a functional home which remains a tribute to their endeavours. We are happy we followed that trail.

Sustainable designed and constructed our new Recipe Home at Boonah. Brett and his team at Sustainable have been very professional to deal with during the design and construction phase. They have provided the total solution for our property using an overall masterplan. The plan has been staged to provide the infrastructure, landscape and land management for the integrated design of our house. Their practical skills and knowledge in the building industry, which has come from years of designing and constructing all forms of the built environment from houses to landscapes, is evident. The key for us was that the dwelling did not separate us from the rural landscape and they have achieved this without compromising which is a fantastic living environment for our family.

It was a pleasure to have the team from Sustainable carry out my house and landscape improvements. They were professional at all times while also being friendly and approachable. Nothing was too much trouble and they always kept me updated on the progress of the work. I had peace of mind knowing that the job would be done properly and to the highest of standards. I valued their knowledge and expertise and was confident that they would meet my requirements and do justice to my lovely old Queenslander. My favourite part of the project is the selection of plants they chose and I’m thoroughly enjoying my new garden.

We’re delighted with the work that Sustainable has done for us. We commissioned a holistic plan to rework our old 1960s house and garden. The design process was very helpful and consultative and the plan that was delivered met all our key requests: that it should be affordable, low maintenance and that it should use wherever possible, native fauna and recycled timber. The design solution to our front yard that you came up with is very clever indeed. Stage one has just been completed and we’re very happy with the results. The backyard was an unusable, weed covered wilderness. It has now been beautifully, and cleverly landscaped in a low maintenance and water-wise way; and we’re looking forward to seeing how it flourishes over the next few years as the plants and trees grow and spread out. Our kids have reclaimed it as a play area, which is very gratifying to us. You made the process very easy and we have already recommended you to some friends. We’re very much looking forward to proceeding with the next stages of our plan with you. You guys are first rate.

We designed an outdoor learning space that fits into the overall master plan strategy and combines the observed needs from the kids with multifunctional and safe outdoor learning facilities. The design also reflects the integration of solar gaining for lighting and water storage with gravity feed irrigation to make the space low maintenance and self sufficient… “I was extremely impressed with the fact that Sustainable came to the site, prior to starting, to observe the children playing in the area. This allowed them to come up with a design that was aesthetically beautiful yet practical and would remain beautiful in the future. Mt Crosby State School is, I feel, unique in that the children have gardens to play in, not just around, and Sustainable have captured this in their design. I have not heard of any other company taking the time to do this type of research.

Donna Cains – P & C Operations Manager @ Mt Crosby State School

I was very impressed with the quality and service of Sustainable. They recommended that we plant some trees around our pond to attract some honey birds. They were right; we have beautiful birds that visit our garden everyday! Especially the work of Terri from Sustainable, she was very energetic and enthusiastic, no job seemed too large! Very happy with the end result, we even have cars stopping in the street to look and admire our garden.

Wendy Auton – Landscape client @ Treetop Close

I have worked with Sustainable on several projects for non profit organisations, they are polite, professional and do a fantastic job. They have a good knowledge of funding agreements and government regulations regarding building, landscaping, infrastructure and water conservation which made them a great company to do business with.
