Sidney Kahn House, Modernist residence in Telegraph Hill, San Francisco, US.

Sidney Kahn House is a four-story modernist residence in Telegraph Hill with balconies facing south and east. Built with a steel and wood frame, it sits on a rocky base and features large windows that open toward views of the Financial District and the bay.

Richard Neutra designed the Sidney Kahn House in 1939, not 1940, for Sidney Kahn. The four-story house was later split into two smaller units by a subsequent owner before being reunited into a single residence. It stands near 42 Calhoun Terrace, where Diego Rivera and Frida Kahlo lived briefly in 1940.

The Khans commissioned Neutra to design furnishings along with the house. The best-known result is the "camel" table, whose legs could kneel to lower it to coffee-table height. The house stands near 42 Calhoun Terrace, where Diego Rivera and Frida Kahlo lived briefly in 1940.

The house is a private residence and not open to visitors; it can only be seen from the street. It stands near 42 Calhoun Terrace, where Diego Rivera and Frida Kahlo lived briefly in 1940, so the surrounding lanes of Telegraph Hill can be combined in one walk.

The house emerges directly from the rocky base, with Neutra designing the structure to appear as if it grows from the stone itself. This approach to merging with the natural terrain was innovative for residential architecture of that era.
