Back in 2012, a modest 2-bedroom, 1,668-square foot single-family home in Noe Valley sold for $570,000. The buyers set about tearing down almost the entire house and building in its place a modern, massive 3,644 square-foot, 4-bed, 4.5 bath abode with five view decks and an elevator to all levels. A floating wood and glass staircase passes through a retractable skylight as the home's main interior feature. The backyard has a vine wall and desert garden, while inside there is solar-powered radiant heat, a Sonos sound system, and Nest thermostats. The nearly all-new house is on the market for $3.599 million.
