About Us

Homes for Our Future

Custom Green is a design and building company specialising in energy efficient and passive solar sustainable homes. With a little extra care upfront, our homes produce lifelong rewards for occupants: think reduced energy bills, a smaller carbon footprint, less waste and homes that are comfortable all year round. And they are not necessarily more expensive to construct than a standard home.

Our experienced team consider every detail so, together, we can make a big difference. From low-cost holiday homes through to large, luxurious family homes, our holistic approach is changing the building landscape in WA for the better.

As a small team we offer an outstanding service where you will be walked through the full design and build process. To ensure there are no surprises down the track, our site manager and project manager will be involved right from the outset.

While our strength is in designing and developing from concept to completion, we can start working with you at any stage of your project.
