About this home

Located in Frankston South on Bunurong Country and backing onto Narringalling (Sweetwater Creek), Sweetwater House provides flexibility and sanctuary for our family of four. Designed and built during Melbourne’s Covid lockdowns, the home reflects an inventive response to low-cost, multi-generational living while telling a story of personal and ecological renewal.

Drawing on knowledge and experience gleaned from previous mass-timber projects, the home was constructed using a prefabricated construction methodology.

Our ambition was to create a materially honest and highly sustainable home. We developed a plan arrangement that could adapt to the changing needs of two teenage children and allow for multi-generational living. The gravitational heart is an open plan living room and kitchen overlooking the creek. Encircled by tree ferns and eucalypts, the home’s warm timber palette nurtures a sense of welcome and calm.
