Carrie Bradshaw could be moving to the Upper West Side. After almost a year of house-hunting, West Villager Sarah Jessica Parker is considering a sprawling, $21 million duplex pad for her brood at posh 88 Central Park West, reports The Post’s Jennifer Gould Keil. Despite rumors that Parker had signed a contract, a friend cautioned, “This isn’t a done deal yet.” Parker’s rep declined to comment. The building is home to “Saturday Night Live” creator Lorne Michaels. There would be lots of space if Parker and hubby Matthew Broderick decide to raise their kids there. “There aren’t many apartments this big, with eight bedrooms, on Central Park West that are on the market. In fact, there aren’t any at all,” said a broker who walked through the apartment. It boasts a 32-foot living room, and 10-and-a-half foot ceilings but also has a “funky layout.” It was most recently owned by the philanthropist Laurie Tisch, who has since bought at 834 Fifth Ave. Meanwhile, Parker looks ultra-sexy in a photo shoot for Elle. She tells the mag: “Yes, I am aging. Oh my God, I’m aging all the time. But what can I possibly do? Look like a lunatic?”
