Rob Kennon Architects reimagined a California-style bungalow for a family in Melbourne’s Elwood suburb, taking inspiration from renowned Australian architect Sir Roy Grounds’s Hill House, which features a circular, glass-walled courtyard within a square of solid brick walls. The single-story extension to Elwood Bungalow similarly encloses a circular courtyard with an artfully planted garden. Inside, the cost-effective material palette includes walls of recycled masonry and a concrete ceiling and floors that complement the original home.
