A modern home set atop the highest residential point in San Francisco made headlines when it landed on the market in 2020 for $22 million. At 900 feet above sea level, the four-story pad’s bold, boxy façade is poised to take advantage of the epic views of local landmarks such as the Golden Gate Bridge and Alcatraz Island. The local firm John Maniscalco Architecture designed the extraordinary build, which is now on the market for a smidgen under $20 million, $2.1 million less than its original asking price.
