About this home

Magpie House is an all-electric, Passive Solar design (8.2 star NATHERS) knock down rebuild of a typical Canberra ex-govie in Watson, completed by an owner builder from 2018-2020. The 180 square meter dwelling uses the traditional Passive Solar design approach of manipulating orientation, glazing, thermal mass, mechanical ventilation and insulation to minimise energy consumption to maintain thermal comfort.

In combination with these approaches, 10kw of PV solar, an electric car charger, Hot water heat pump and energy efficient lighting and appliances, enables Magpie house to not only be net energy positive, but economically positive in its energy and transport energy costs throughout the year.

The existing house on the site was slowly dismantled and valuable, recyclable materials were diverted from landfill and have since served as the basis for joinery, furniture, and architectural detailing in the new build.

Other aspects of the build that visitors may find interesting include, integrated acoustic surfaces/finishes, reverse brick veneer construction, slab edge insulation, automated ventilation systems, DIY concrete countertops, Low VOC finishes, honeycomb blinds, custom light fittings, and self built kitchen/joinery.

No wheelchair access at this property.

Q & A

What motivated you to build or retrofit sustainably?
Thermal comfort, affordability
Designing a layout that optimises the benefits of Passive Solar Design. Passive Solar design allows our house to leverage the natural climactic variations of our environment to improve thermal comfort, and reduces the need for external heating and cooling inputs.
Being more selective with professionals who hold critical administrative roles in the build process: in our case Building Certifiers. Our Certifier was de-registered mid-way through the build process leaving us in a stressful administrative bind at the completion of our build.
Either: Exchanging our plug-in Hybrid for a full Battery Electric Vehicle with Vehicle to Home technology OR
