Sanctuary Circle 2019

House Notes – Sanctuary Circle

Sanctuary Circle is a vernacularly designed, passive solar home. Specifically designed to suit the Cowaramup climate, it is a home that will stay comfortable all year round with minimal artificial heating/cooling. The home was designed for a block with an awkward layout as well as a relatively steep slope to the rear of the property. North is orientated towards the street and, therefore, the layout of the home is crucial.

There is a fireplace in the living area for winter, but no air conditioning is required. A concrete slab is coupled to the ground to minimise temperature fluctuations and has well-insulated external skin.

The home is greywater-ready and has a large rainwater tank feeding the whole of the home except showers.

It is built to BAL29 to reduce the threat of bushfire damage.
