Architectural studio WALA revived a Federation-era bungalow in Melbourne with a two-level extension that incorporates a rear garden and addresses the home’s flood-prone site. At the rear of the home, full-height, sliding glass doors open to a raised deck that connects to a self-contained pavilion with a study and second living room. The large, rear courtyard is anchored by a Japanese maple tree that works to harmonize the old and new buildings.
