Message to Brad Pitt: if you’re reading this, Dion Neutra, AIA, has a business proposition for you.

Neutra, son of the late California modernist Richard Neutra, is looking for someone to buy his firm’s former office, in Silver Lake, California. Completed in 1950, it is now his father’s only surviving commercial structure. The asking price is $3.5 million, but there’s a catch. In addition to paying all-cash, a buyer must agree to leave the landmarked property untouched—or risk losing the deed.
