660 Fifth (New York City, New York)

 office building, skyscraper, commercial building

483-foot, 39-story International-style office building completed in 1957. Designed by Carson & Lundin, it was known as the Tishman Building, for the Tishman Realty & Construction Corp. which sold it when the corporation dissolved in 1976. 666 Fifth Avenue was bought by Sumitomo Realty & Development in the late 1990s, and Tishman Speyer bought it back in 2000, adding tenants before selling it yet again to Kushner Properties in 2007 for a record $1.8 billion, the highest price paid for a single office building in the United States to date.

The facades were originally clad in aluminum and glass, with embossed aluminum spandrel panels, with each bay having tripartite windows. The 2-story base (three stories at the northeast corner) has large storefronts. The 3-story northeast corner of the base is fully enclosed in glass. Toward the middle of the north and south facades on 52nd & 53rd Streets are the main entrances, both deeply recessed with revolving doors. Next to the north entrance is a subway entrance. The westernmost bay on 53rd Street has an entrance/exit to the underground parking garage, and the next three bays have loading docks.

There is a major setback above the 7th floor at the west half of the building, and above the 9th floor at the east half. Additional setbacks above the 10th and 14th floor, give way to the main upper tower, a slab oriented east-west. It has 22 bays along the north and south sides, and 10 bays on the east and west. The tower originally had large red numbers "666" at the top, which were replaced by the Citigroup logo in 2002.

The ground floor is occupied by a Citibank branch, Zara clothing store, Tissot watches, and a Uniqlo clothing store. The exterior was reclad in 2021 by Kohn Pedersen Fox for Brookfield Properties. As part of the renovation, the remarkable lobby was dismantled and placed in storage. The new cladding is blue glass arranged in horizontal rectangular window panels, with thin metal framing. The base spans 11 of these panels along the Fifth Avenue frontage, with the upper tower spanning five panels on the east and west sides, and 11 on the north and south.
