EHAUS EURO, PASSIVE HOUSE CLASSIC

Roxborough

30,329 KG

89%

It’s remarkable how much fits inside this two-storey 151 m² home for an extended and expanding family. The clients wanted a functional and compact home, a place that was both dignified and comfortable. It also includes a self-contained flat, gym, library and 3.5 bathrooms "Without a doubt the most comfortable house we’ve ever lived in, year-round and without having to burn power to make it that way, which is awesome"
