Madonna has expanded her New York City base, paying $7,000,000 for another co-op unit that will expand her existing two-unit spread in a building on Manhattan's Central Park West.  The New York Observer's Lysandra Ohrstrom broke the story on Wednesday of Madonna's closing on the seventh-floor apartment in Harperley Hall, which is at 1 W. 64th Street or alternately at 41 Central Park West in Manhattan. Indeed, a deed filed on Wednesday showed that through her own name, Madonna purchased unit 7A in the building. The deed gave Madonna's address as 6A in the building, and Ohrstrom noted that Madonna's existing 6,000-square-foot duplex now will expand significantly.  Madonna had gone to court to acquire this unit, which will be the third apartment in the building that she has purchased and combined. In December, Madonna sued the building's co-op board for trying to block her purchase of it. Madonna has owned in Harperley Hall since the late 1980s, not long after she was famously rejected by the San Remo building's co-op board. The New York Daily News' Rush & Molloy column previously had first reported on April 10 that Madonna had gone to contract on the unit. Madonna continues to own plenty of real estate in England. Stateside, her only other known parcel is a 5,800-square-foot (according to public records) or a 16,500-square-foot (according to the Los Angeles Times) house on a 1.18-acre parcel at 9425 Sunset Boulevard in Beverly Hills, Calif. that her Castillo Del Lago Trust purchased in 2003 from actress Sela Ward for about $12 million, according to public records.
