The Roy Grounds House, at 24 Hill Street, Toorak in Melbourne, Australia, was designed by Sir Roy Grounds as his own home for his wife Betty and himself. It is celebrated as one of the most outstanding works of modernist domestic architecture of the mid 20th century in Victoria, a time of great experimentation, and one of the most notable designs by Roy Grounds, one of the most well known and influential modern architects in Victoria.

Sir Roy Burman Grounds was an Australian architect. His early work included buildings influenced by the Moderne movement of the 1930s, and his later buildings of the 1950s and 1960s, such as the National Gallery of Victoria and the adjacent Victorian Arts Centre, cemented his legacy as a leader in Australian architecture.
