Walsh Street House, Modern house in South Yarra, Melbourne, Australia

Walsh Street House is a modern residential building in South Yarra featuring two separate pavilions connected by a central courtyard. The structure displays a cable-supported roof and glass walls throughout, blending interior and exterior spaces visually.

Robin Boyd designed the house in 1958, and the family moved in a year later. The design drew on International Style functionalism and the structural optimism of Spanish engineer Eduardo Torroja, expressed in a draped roof slung over cables. In 2006 it received the RAIA 25 Year Award at state and national level and is listed on the Victorian Heritage Register.

The house is named after its street in South Yarra, and Boyd designed it as a family home for himself, his wife Patricia and their two daughters. The plan separates an adults' wing at the front from the children's quarters across the courtyard, a division Boyd had already considered in his first Camberwell house.

The house is a private family home, not open for casual visits; access is arranged through the Robin Boyd Foundation, which uses it as its base. The plan is introverted, with most views turned to the internal courtyard, so little can be seen from Walsh Street. A large Monterey pine stands at the front, and the sloping site means the entry stair rises from ground level to the first floor.

The house sits on what was once a small side garden of a larger allotment. A large Monterey pine (Pinus radiata) stands at the front, and Boyd shaped the design around the tree to keep it standing.
