David Sellers, a maverick architect who helped start a movement based on the radical idea that structures turned out better if they were built by the people who had designed them, died on Feb. 9 in Los Angeles. He was 86.

Naming the place Prickly Mountain, in honor of the wounds a friend had suffered after sitting on a raspberry bush, they began to build.
