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. A columned front porch invites you inside, where the foyer leads to a soaring, two-story living room with fireplace and gently curved 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.
