House Notes – Kingfisher House GC

The home is designed as part of a master planned estate on residential land in an existing suburb. The clients purchased the land to enable them to develop a more sustainable lifestyle for themselves, and demonstrate the potential of that to others.

The site includes master planning for future provision for higher density to better use the land, edible and productive gardens with market stall, a home which is designed for extended family / intergenerational living / co-housing, and renovation of an existing granny flat to further enable the land to be well used. The home itself is designed to respond to the local climate with passive solar design, well insulated, tight sealed, double glazing – as well as active systems such as hydronic heating, pv, battery, car charging, all electric home, mechanical ventilation system (rough in for future install), efficient ac system (for better air filtration), controlled climate in a central courtyard to allow outdoor lifestyle in inclement weather and to allow both sides of the home to be left open for better cross ventilation (and so on).
