Sydney’s first Certified Passive House home, designed for a family with two school-aged children.

The main living area is open to the backyard via a sliding door and three bedrooms upstairs. Construction started in February 2019, and it is only recently finished. As it is a newly built premises we are yet to determine the actual running costs and footprint.
There will be a blower door test at 10am and 11am for those who wish to witness one.
