Liebermann, who apprenticed with Frank Lloyd Wright, had a cult following for his organic structures, several of which are in Mill Valley. Still practicing today, he was a very early preacher of green building.
In his own home, he implemented his vision of the ideal architecture, which has turned out to be remarkably prescient. “I was thinking about how to disrupt the site as little as possible,” says Liebermann, who is just shy of 80 today. Instead of maximizing what he could build on the steep, heavily wooded hillside, he created a shallow excavation—what he describes as a “bite out of an apple.”
