Ayn Rand lived in a house designed by a renowned modernist architect, Richard Neutra. You can find more information about Neutra's work at the Neutra Institute for Survival through Design. Merrill Schleier, the author of the article I gave you about The Fountainhead, has more to say about Rand's relationship to modernist architecture here. Alas, the house she lived in, the Von Sternberg house (designed 1934) was demolished in the seventies. You can see Julius Sherman's photographs of the house in a slideshow here, as well as read an account of its interesting history; more images of Neutra's work here. The picture below is of Rand (and her husband, Frank O'Connor) in situ.
