Energy Efficient Architecture
The house is all-electric with a 9.6kW solar system and 9kw LGchem battery system. It is energy positive for all but the coldest months. Heating is via solar heat pump hydronic heating in the insulated slab. The insulation and design means there is no heating system needed upstairs. Hot water comes from an efficient heat-pump to minimise energy use. Ceiling fans cool the living areas and bedrooms. Large doors and windows give good cross-ventilation to purge hot air.The double-height entry acts as a thermal chimney, venting warm air as it rises from the living areas. Triple-glazed composite windows complete the energy efficient design.

Rammed Earth Entry
Craftsmanship and thermal efficiency combine in this double-height entry space. Acting as a thermal chimney, it also showcases the owners’ love for timber joinery and custom detailing. The rammed earth wall acts as a tactile guidepost, leading the visitor through to the rooms beyond.
Storage, space and function
The kitchen balances large amounts of storage with generous circulation and preparation space. A home office is hidden behind sleek cabinetry. Laundry, pantry and wine storage nestle in the thermally-stable heart of the home, behind rammed earth walls. The kitchen is the social hub of the house, with connection to all living areas, including the outdoor deck.
The generous north-facing triple-glazed slider connects onto the adjacent outdoor living area. This effectively doubles the size of the living room and maximising solar gains in wintertime.
The house features custom timber joinery and recycled timber – a mix of the owner’s craftsmanship and the builders’. The timber and rammed earth bring warmth and texture to the otherwise minimalist palette.
