About Gundaroo Passive House

This rural sanctuary comprises of an open plan living, 3 bedroom, 2 bathroom house plus a shed and self contained studio, all with a stylish modern aesthetic.

The home has been built to Passive House standards meaning it performs perfectly in retaining a comfortable interior temperature (relative to the exterior temperature) without any heating or cooling required. The high tech battery operated solar power supply means this home is off grid and completely self sustainable when it comes to the little energy it consumes. The supply of water for the home is through the integrated rain water tank system.
