The Malloch Apartment Building is a prominent example of Streamline Moderne residential architecture in San Francisco, characterized by aerodynamic horizontal lines, rounded volumes, and a light, ship-like appearance that earned it the nickname “the Ocean-Liner House.”
Designed by Irvine Goldstine, the building consists of four residential floors above two lower levels supported by reinforced concrete to meet seismic requirements, while the main structure above is wood-framed. Its most distinctive features include a tall glass-brick elevator shaft, a sand-etched glass panel above the entry, and three large Sgraffito murals by artist Alfred Du Pont, depicting a Spanish explorer, a worker with a globe, and a female "Spirit of California".
The integration of sculptural decoration and streamlined forms has led architectural surveys to recognize it as one of San Francisco’s most significant examples of the style.
