About this home
This extraordinary estate with a beautiful Georgian Federal-style home was designed by the American architect Allan Greenberg for world-renowned tennis legend Ivan Lendl. Ride through the gates passing horse paddocks, a barn, and up a long and meandering driveway to the impeccable stone house. Enter the first floor passing a grand staircase to a light-bathed main floor with virtually every room boasting French doors to beautiful gardens and patios. A wood-paneled library, spacious living room, formal dining room, and family room, all with fireplaces and wide plank oak floors, as well as a trophy room/office and an eat-in chef’s kitchen with state-of-the-art appliances and butler’s pantry complete the 1st level. The primary bedroom suite with 2 oversized walk-through closets, a sitting room, and a luxurious oversized bathroom accompanies an office with a paladin window, a children’s library, and 3 additional ensuite bedrooms on the 2nd floor. The third floor has 5 en-suite bedrooms. Additional indoor amenities include an indoor pool adjoining two locker rooms, a sauna, a workout room, and a full-sized gymnasium. Outside there is a heated gunite pool with a cabana, tennis court, and play court. The attached 3 bay garage is complemented by a 3 bay detached garage with office space on the second floor. All of this, overlooking the Connecticut foothills.
