The humble Granny Flat

The humble “granny flat” has had a serious makeover in the last decade with these second homes being used as anything from an AirB&B short-term rental, to a teenager’s escape, or a safe place for relatives to live close by.

Built To Stand The Test Of Time

ADD Granny Flat homes use timber and steel framing to stand the test of time, as well as colorbond roofing and stainless steel kitchen appliances.

The final product is one that not only reflects your personal style, but one that has been proven to give the best results.
