The house is a typical passive solar home with earth bricks, made onsite, providing almost all of the thermal mass. The north aspect provides maximum solar access for passive and active solar energy capture and passive storage. The photovoltaic system produces, on average, three times more power than the household uses. The composting toilet system, as well as other water saving features, give the means for water self sufficiency.
The curved roof was the first to go up making it easier for the non-load bearing earth brick walls to have protection while being built. This ‘slow build’ makes it a more viable and affordable project for the owner builder. The build style also allows for aesthetic and practical changes to be incorporated during the build, which contributes to a better outcome and less overall stress.
Apart from some plantation softwood, all timber used is recycled hardwood. The paint and finishings contain low or no V.O.C.s. All furniture is pre-loved and or made from recycled timber, including a daybed made from recycled wine barrels.
The property produces much of the household’s fruit and vegetable needs with compost generated from materials gathered on site. The owner was careful not to plant any exotic that may pose an invasive risk to local native plant communities.
