Wandilo Green

During 2015 we decided to buy ourselves a block of land out of town. Our aim in life was to build for our children and ourselves a better lifestyle, where we could all enjoy the outdoors much more.

We are passionate about leaving a small footprint on the planet and decided, if we were going to build, then we were going to implement as many sustainable building techniques as we could.

Now we enjoy no gas, electricity or water costs. Our house also stays at a relatively even temperature all year round. We love it here and look forward to implementing more ideas in the future.

House built by Peter Cavanagh Homes.
