Off-grid Orange House 2024

House Notes – Off-grid Orange House

Nestled on the outskirts of a vibrant country town, this 19-acre property provided us with a blank canvas to build a sustainable and innovative family home.

The resulting home design seamlessly integrates with its surroundings, offering functionality, climate responsiveness, and remarkable energy efficiency, with a 7.1 star energy rating in a challenging climate zone.

Driven by a passion for low-impact, eco-friendly living, we incorporated a 14kW solar panel system and a 40kWh battery for both home and car power. A geothermal heating system, extensive rainwater harvesting, and reed bed wastewater treatment helps meet our commitment to lowering our environmental footprint.

We have adopted a regenerative agriculture approach, embracing native revegetation and permaculture principles to become more self-sufficient, while also making choices that pave the way for a more sustainable future for generations to come.
