1) East Hampton: Architect-slash-bon vivant Peter Cooke has put his house (right)—a stone's throw from Georgica Pond on Briar Patch Road—on the market, asking $19.95 million. Exudes Dan's, "The listing has raised a few eyebrows. Is he leaving or is he downsizing? Would be a shame to see him go, he's great." UPDATE: We're told by insiders it's not Cooke's own place, but rather just one of the thousands of houses Cooke designed. Exhale. [Corcoran, Dan's Blog]
2) East Hampton: Meanwhile, Real Housewife Kelly Killoren Bensimon has yanked her 8,500 square foot house from the market (it had been asking $10.9 million). Summer rental available, though, for those who must. [Real LI]
3) Amagansett: At the slightly less aggressive end of the East End real estate spectrum, British actress Emily Mortimer and husband Alessandro Nivola scooped up a vintage farmhouse for $980,000. As helpful context, New York Magazine adds, "They also own in Brooklyn." [NYMag]
