The Dunsmuir mansion, designed by San Francisco architect J. Eugene Freeman, is an example of Neoclassical-Revival architecture popular in the late 1800s. The 37-room mansion once owned by the Hellman family, features a Tiffany-style dome, woodpaneled public rooms, 10 fireplaces and inlaid parquet floors within its 16,224 square feet. Servants quarters in the house are designed to accommodate 12 live-in staff. Golden Gate Park's landscape architect, John McLaren, is said to have assisted the Hellmans in designing the Dunsmuir gardens. A wide variety of trees, including Camperdown Elms, Bunya-Bunya and Hornbeam, still grace the estate's gardens and expansive meadows. In addition, the Hellman estate contained a golf course, formal croquet court, tennis court, swimming pool with Mission-style bathhouse, glass conservatory with grotto, an elaborate aviary, formal garden maze, and Japanese garden.
