At the end of a cul-de-sac on a little traveled street in Bridgehampton South, two contiguous properties comprise 4.6 total acres - a gated 2.6 acre parcel with a superbly elegant 13,000+/- sq. ft. estate and dock on Kellis Pond, and an adjacent vacant 2 acre parcel with water frontage on the pond. Past the gate at 164 a driveway passes through lush and beautifully landscaped grounds where broad lawns underlie stately trees and are surrounded by borders of colorful flowers and shrubs. The front porch invites you inside, where the foyer leads to a soaring, two-story living room with fireplace and wall of French doors opening to a stone porch extending across the rear of the home. Off the foyer is a library/den with fireplace, a bar area and a powder room. Formal dining adjacent to the living room flows to a butler's pantry and chef's kitchen, both of which have granite countertops and high-end stainless steel appliances. Glass doors open from the kitchen to a glass sunroom with dining area. A guest wing has three en-suite bedrooms, all with marble baths, and an office. Upstairs a private aerie is devoted to the master suite, composed of a sitting room with fireplace, bedroom with glass doors to a private water-view terrace, two walk-in closets and sumptuous white marble bath with spa tub, huge glass-enclosed shower and double vanity. In the finished lower level find a temperature-controlled wine cellar, gym, recreational room, living room and two en-suite bedrooms. Additional amenities include two-car garage and cabana with steam room and wet bar. Outdoors in the exquisitely landscaped grounds are many places to relax or entertain. A rear stone terrace with both open and covered areas overlooks the 50' pool and waterfall, poolside patios and gardens of colorful flowers. At water's edge is a dock. Find peaceful seclusion and luxury in this very private estate, where you will also be just a few minutes to Bridgehampton's hamlet center or the ocean beach.
