It’s not your typical Silicon Valley home. In San Jose, Calif., a property asking $3.68 million sits on roughly 30 acres atop a mountain ridge.
The seller is Charles Armstrong, 41, a product manager at Google. Mr. Armstrong said he bought the empty plot of land, at an elevation of approximately 1,600 feet above sea level, in 2016 for roughly $650,000. He said he spent about five years developing it into a home for his family, installing everything from a septic system to a well to an off-the-grid solar system. He even paved the roads that lead up to the house.
