Another New Penthouse For Chris & Gwyneth

Gwyneth Paltrow, a mother with two young children who also occasionally appears in films, is still in a nesting phase.

Two years ago, she and her rock-musician husband, Chris Martin, bought a condo with 7,000 square feet of space on three-and-a-half floors in a small two-unit building in TriBeCa for $7.95 million. In August, they bought a summer house in Amagansett, N.Y., for $5.4 million.

And then at the end of 2006, Ms. Paltrow signed a contract to buy the last unsold apartment at River Lofts in TriBeCa, a 4,400-square-foot sixth-floor penthouse with three bedrooms, three-and-a-half baths, a library and two terraces. The sale was put at just over $5 million, somewhat below the $5.5 million asking price. The River Lofts project comprises a restored five-story warehouse with new penthouses on top on Washington Street and an adjacent new 13-story building on Laight Street.

Brokers from the Sunshine Group, which marketed Ms. Paltrow’s apartment for the developer, Shaya Boymelgreen, declined to comment. It was not clear why Ms. Paltrow and Mr. Martin, the lead singer and guitarist of the British rock band Coldplay, had the real estate itch once more. Stephen Huvane, her publicist, declined to comment. “Sorry, but we cannot confirm or deny,” he said.
