Portrait artist Chuck Close and his wife Leslie paid $5.95 million for a cond-op unit at the Deborah Berke-designed 48 Bond Street in Noho. The sale by photographer Gary J. Cooper closed on October 6, according to property records posted today. The couple also owns a 2,500-square-foot cooperative nearby at 20 Bond Street. Close, 68, was critical of development on Bond, which he said threatened to shut out sunlight, rendering his studio unusable. Cooper and his wife bought the apartment in the 17-unit building in April for $5.25 million, but never moved in, Cooper said.
