Immediate access to boating is a huge commodity on the East End — and a clear factor in the $12 million sale of 29 Cobb Isle Road in Water Mill.
The six-bedroom, 7,650-square-foot, shingle-style home sits on 1 acre of waterfront property, surrounded by gardens and mature trees. The architectural design by McDonough & Conroy takes advantage of the private setting. Indoor/outdoor living is created by principal rooms having views of the bluestone patios and porches.
The first floor includes a two-story foyer, a living room and dining area separated by a two-sided fireplace, a large great room with a fireplace and a separate waterside lounge, and an oversized kitchen. There is a large TV room with a wet bar, a powder room and a staff area with an en-suite bedroom. On the second floor, there are five en-suite bedrooms — several with sundecks — and a large game room.
An 18-foot-by-40-foot heated pool and pool house anchor the outdoor space, which leads to 275 feet of bulkheaded waterfront property and a floating dock, perfect for a powerboat, jet skis, kayaks and paddleboards.
Sotheby’s International Realty had the listing, which sold on October 29. The seller was Michael Gross, though the buyer’s identity is shielded by a limited liability company.
