Brett and our Sustainable Team finished building Tobias Volbert and his family’s dream home, the Kingfisher, in 2017. Now, 3 years on, Tobias shares his story of living in their sustainable Kingfisher Home.

Wow! 3 years ago we moved into our sustainable Kingfisher Home…it still feels like a dream! We’ve experienced now 3 summers and 3 winters and can truly say that the Kingfisher performs without air conditioning and heating.

Even on the warmest summers days we get a breeze and the kids often call it “The Wind House” – a testament that the cross ventilation works to perfection! The amazing and innovative insulation process with the thermal chimney wall system, does its trick. It provides a house that stays cool in the summer months and passively heats during the winter, holding the heat coming from the thermal mass of the sleeping area of the house.

We also love our electricity bill that comes in under $100 per year, and our water bill is keeping at the minimum as the tanks (25,000 L) have never been empty so far.

It’s incredible how the house works for us as a family and Brett was so right by explaining the importance of volume vs m2 as well as ensuring that home spaces are multi-usable and flexible. The entire property has now different rooms inside and outside to engage, find refuge, entertain or reflect. It just works superbly!

Also, how fast did our forest grow?! Unbelievable that now we sit on our deck and look into a proper forest just after 3-4 years. And the wildlife we are attracting…so good!

Brett and the Sustainable Team, once again, thanks for making our dream come true!!

[The Kingfisher Series] Podcast Video 4 – Why are we still creating developments on “life support” in 2020?

Brett McKenzie sheds light on the reality of today’s housing developments. Here at Sustainable we aim to inspire people to take on the responsibility to create design lead homes that create better community living rather than contribute to larger social and environmental issues.

Brett: “So yes the housing stock may be cheaper, but effectively you are buying cheaper products [and] a cheaper system. In the long term, if you have a design lead process with long term thinking, you end up with a more cost effective home diluted over a longer period of time.
