Perhaps one of the most famous architectural photos of all time. Certainly it is one of the most famous of modern architecture, and likely introduced many to this new mode of design and its new architectural ways, forms, and materials. It was built in 1957 as a Case Study House, which themselves are an interesting thing, some 36 home designs sponsored by Arts & Architecture magazine as experiments in American residential architecture. This one, the Case Study House #22, overlooks Los Angeles by dramatically cantilevering the glassed-in and nearly transparent living room over the edge of the cliff, something this photo by Julius Shulman does wonders to highlight. To the eyes of the day it must have appeared completely otherworldly.
