Spanish retailer Inditex SA said it bought the former NBA Store at 666 Fifth Ave. in Manhattan for $324 million, in a record deal for a US retail property.

The company will make the 39,000 square-foot storefront between West 52nd and 53rd streets into a flagship store for its Zara clothing chain, Arteixo, Spain-based Inditex said yesterday. The site was the home of a National Basketball Association shop that sold team jerseys and other memorabilia.

The transaction values the space at about $8,300 a square foot. That exceeds the $8,000 a square foot paid in 2008 for a 6,000 square-foot retail outlet at 713 Madison Ave., according to Real Capital Analytics Inc., a New York-based company that researches commercial property sales worldwide.

The 41-story tower that houses the store, completed in 1957 and originally known as the Tishman Building, has been the site of two other price records since 2007. Kushner Cos. paid $1.8 billion for the building that year, then a record for a single US property. Last year, the parent of Japanese clothier Uniqlo rented retail space at the building for 15 years for $300 million, the most expensive lease for a New York store.

The site, near Rockefeller Center, is “one of the major fashion shopping areas in the world,” Inditex said yesterday.
