Tiffany Building, Retail building at Union Square, San Francisco, United States

The Tiffany Building is an eleven-story retail structure at Union Square with a spacious flagship store on the lower levels and office spaces above. The layout makes efficient use of this prime central location.

Skidmore, Owings & Merrill completed the building in 1972 for Qantas, respecting Union Square's 140-foot height limit. It was designed as a background building between two Classical structures. Qantas Investments US Inc sold it in early 1996, and Cathay Pacific moved its North America headquarters there in 2005.

Cathay Pacific moved its North America headquarters into Suite 300 in 2005, and the airline held a grand opening on February 15, 2005, with a ribbon cutting, a roast pig cutting and a lion dance; Mayor Gavin Newsom proclaimed that day "Cathay Pacific Airways Day in San Francisco." The Consulate General of Tonga was also housed here before moving to Burlingame in 2014.

The building opens directly onto Union Square, a location with excellent public transit connections and abundant foot traffic. The site is easily accessible on foot and sits in the middle of the commercial district.

The Art Deco granite arch and stainless steel door belong to the Tiffany & Co. store that opened in October 1991, built by Werner & Sullivan and designed by John Loring with a company committee. The store moved from Grant Street and more than doubled in size, from 8,000 to 17,000 square feet, making it the company's second largest after New York.
