Input: Text:  One Front Street also known as Shaklee Terraces is an office skyscraper in the Financial District of San Francisco California. The 164 m (538 ft) 38-floor tower was completed in 1979. The composition of the façade closely resembles that of the Shell Building by Emil Fahrenkamp which was built in Berlin in 1931. The Shaklee Corporation was once headquartered in the tower until the company moved to Pleasanton California in 2000.
