Stahl House, Hollywood Hills

In 1959, Buck Stahl bought a piece of cliffside overlooking Los Angeles for less than $14,000. He envisioned a residence made of glass that would offer panoramic views of the city below.

It took a while, but he finally found an architect mad enough to give it a try. The resulting house, built by the now-famous Pierre Koenig, is a marvel of gravity-defying design.
