An 18,000-square-foot, $12.9 million estate is taking shape on Rose Hill Road in Water Mill. After some intense Streeteasy stalking, we conclude that the McMansion's 2.5-acre parcel was purchased earlier this year for $2.3 million. But what could an East End builder possibly use to fill 18,000-square-feet of living space? Other than 10 bedrooms and 16 bathrooms, lots and lots of home appliances! In the main house, cook up a storm with two Sub Zero refrigerators, two Wolf Range stoves, a separate wet bar, and a wine cellar. Make a mess? Clean it all up in one of four laundry rooms. But wait! Sometimes you just want to get your grill on. And for that, there's an outdoor kitchen with yet another four refrigerators, a stove, a grilling station, two sinks, and an outdoor dishwasher. We count at least six refrigerators. Is that even legal?
