About this home

A Heritage listed free-standing local-heritage listed (#831) sandstone cottage (43m2 floor area) built around 1874 situated in the South East CBD of Adelaide, renovated with a newly constructed (during 2018) rear extension (46m2 floor area), designed and built around sustainable principles to achieve an overall rating of 7.2 Stars (NatHERS).

The house is fully electric and we drive an electric vehicle, so overall we are ‘net zero’ in terms of scope 1 (direct) and 2 (indirect) CO2 emissions – this is our ‘new normal’. We have moved to time-of-use tariffs from a local energy retailer to make use of cost savings by shifting loads to low-priced times, and any grid power that is purchased is 100% renewable energy.
