Enormous Gold Coast Estate in Mill Neck Asks $21.9M

Summer Hill, an enormous, newly-built Long Island Gold Coast estate, is listed for sale at 315 Mill Hill Road in Mill Neck.

This home is bursting with grandeur on 17.5 acres of gated land. It was designed by Michael Jay Wallin and constructed by Qualico Contracting Corp. in 2011 in the style of a French country house, giving the house both old-world aesthetics and modern luxuries.

There are several sections of this beyond-spacious estate: the main house, the guest cottage, a fenced-in pool area with pool house, and of course loads of outdoor space that includes a large driveway leading to three, connected two-car garages, a reflecting pond with a fountain, a walking trail around the estate’s perimeter, a patio area, and sweeping lawn space.

The estate is guarded by a brick wall and iron gate at the driveway, plus plenty of tall shrubberies. The property has a total of 24 rooms, including seven bedrooms, nine full bathrooms, and four half bathrooms with around 20,000 square feet of living space.

Inside, the main house features a three-story, spiral staircase, a large, formal living room with mahogany French doors, hand-painted murals, and a limestone wood-burning fireplace, 30-foot ceilings in the light-filled family room, a large kitchen with high-end appliances, recreation rooms, a gym, a media room, tasting room/cellar, and more.

Outside, the 20-by-40-foot, an in-ground, heated saltwater pool is accompanied by a cabana with a bathroom, outdoor living room, and outdoor shower.

The 1,500 square-foot guest house is set on its own seven acres and has two bedrooms and two and a half bathrooms. There is potential to expand it up to a 14,000-square-foot home.

The asking price is $21,900,000, not including the annual property tax of $173,277.

The real estate agents listed for the property are Regina Rogers and Robert Olita, of Douglas Elliman Real Estate, who can be reached at 516-759-0400.
