Set on a very private 2.18+/- parklike gated acres, this grand and stately post-modern features 4 large bedrooms (with 2 additional bonus rooms) and 4.5 baths across an expansive 4200+/- sf. The floor plan is easy to love as you embrace the seamless flow of indoor and outdoor living from the glorious front porch to the large deck off the kitchen, living room and primary suite. Upon entering the double-height foyer one is immediately drawn to the grand cascading staircase leading to the second floor. The stunning double-story living room with its grand fireplace is flooded with light from the floor to ceiling windows and doors leading out to the expansive backyard with a 17 X 33 in-ground pool with a brand new liner and piping. The open kitchen will delight all chefs and overlooks both the formal dining room and living room making entertaining a breeze. The primary bedroom suite with its tray ceiling is located on the main level and features his and her walk-in closets, a large windowed marble bathroom, and French doors leading out to a covered porch. There is a junior primary ensuite located on the second level along with 2 additional guest bedrooms plus a small and large bonus room that could easily serve as an additional bedroom, library, and home office. The semi-finished full basement with new egress has high ceilings and plenty of space to convert into the perfect home theater, game room and gym. Two tennis courts (and pickleball) are close by and shared by a limited number of homes that are all part of upscale Grassy Hollow Estates. Additional amenities include an expansive front porch for lazy summer lounging, a walk-in windowed pantry and laundry room, and a large 2-car attached garage. This property represents the best of Hamptons living, where comfort and luxury harmonize in a tranquil natural setting. At the current listing price, 99 Ely Brook to Hands Creek is also a very promising investment opportunity with tremendous upside. By adding a new nitrogen septic system at little to no cost thanks to grants & rebates from NYS & Suffolk County and the Town of East Hampton, 99 Ely Brook can legally become a 6-8 bedroom home with plenty of additional expansion opportunities on the lower level. No finer value exists - must be seen and studied to appreciate. With 4200+/- sf on 2+ glorious acres, this spacious home & property conveniently located to Sammy's Beach, East Hampton Village and town beaches is not to be missed., Additional information: ExterioFeatures:Tennis
