It's important to ask the right questions to ensure you find a builder who takes sustainability seriously. Follow our guide below to make the process easier.

There are lots of environmentally friendly ways to build or renovate – from using recycled or sustainable materials, to incorporating passive solar design, which makes use of the sun for heating and cooling to minimise energy use.

But finding a builder who has sustainable values can require a bit of research. I know, because we are currently looking to upgrade our spare room (housed in a tin shed attached to our house).

While researching online is a good place to start, it’s important to ask a builder (or any contractor) the right questions before choosing to work with them.
