The architect artist credited with this design was Marion Mahony Griffin.

Marion Mahony Griffin (née Marion Lucy Mahony; February 14, 1871 – August 10, 1961) was an American architect and artist. She was one of the first licensed female architects in the world, and is considered an original member of the Prairie School. Her work in the United States developed and expanded the American Prairie School, and her work in India and Australia reflected Prairie School ideals of indigenous landscape and materials in the newly formed democracies. The scholar Debora Wood stated that Griffin "did the drawings people think of when they think of Frank Lloyd Wright (one of her collaborating architects)." According to architecture critic, Reyner Banham, Griffin was "America’s (and perhaps the world’s) first woman architect who needed no apology in a world of men.
