Millthorpe Home Build Off Grid

The project in Millthorpe, NSW was designed and built by Future Build Construction Property Development Pty Ltd to be a self‐sufficient, sustainable, healthy, liveable and energy positive home.

By being able to design and build an energy positive home, it enabled Future Build to achieve a better than net zero result for their clients. We worked with triple bottom line philosophy, aiming to improve on environmental, economic and social sustainability, where and when they could throughout this project.

The home has been designed to minimise the need for auxiliary heating, with no requirement of any additional auxiliary cooling system. The utilisation of the natural breezes through careful design and orientation of windows and doors allows the home to be cooled sufficiently in the warmer months.

Having no access to town water it was imperative to be able to collect and store large amounts of rain water. This was done by installing a 135,000 litre rain water storage tank, where all of the homes roof water was diverted.
