Designed and constructed from the ground up by prominent architect Doug VanderHorn in 2006, Les Arbres is an utterly spellbinding French country manor secluded on almost 4 acres and bordered by almost 78 acres of protected land. The appealing symmetry of the architecture is mirrored in the extensive formal topiary landscaping in the forecourt. Recently renovated in 2021, the baronial exterior opens to reveal a polished 11,870 sq. ft. floor plan with seven bedrooms, eight bathrooms, two powder rooms, and six fireplaces. Blending traditional design with luxurious contemporary style, a glass front door with ironwork detailing introduces the formal entrance, highlighted by Versailles-patterned parquet floors. From the entrance hall, the gracious formal dining room has a marble fireplace and French windows looking out to the west-facing back terrace. Walls of French doors leading to the terrace continue in the stylish formal living room with fireplace and built-in bookshelves. Tucked off the living room is a wet bar with wine refrigerator that adjoins a 1,500-bottle wine room. Paneled in dark stained oak, the magnificent library has a fireplace and built-in bookshelves. Featuring Carrara marble counters, the dazzling kitchen with center island and butler's pantry showcases a five-burner La Cornue gas range, a full-size Sub-Zero refrigerator and freezer, double Wolf ovens and double Miele dishwashers. Two bay-windowed breakfast nooks open to the south-facing poolside terrace with barbecue. Off the kitchen, the sunny family room with fireplace enjoys westerly views over the grounds and opens through French doors to the back terrace. Perfect for indoor/outdoor entertainment, the terrace flanks the south and west sides of the house and offers multiple seating and dining areas. Integrated into the bluestone is a fountained parterre garden as well as an allée of trees. The north and south service wings of the house both have attached garages, one two car and one three car. A mud room with radiant heated floors and its own powder room off the kitchen leads to the northern garage wing. The south wing is fully self-contained, with two garage bays and a separate, one-bedroom apartment. With its own private entrance on the ground floor, the apartment serves as an ideal guest suite with a spacious bedroom, sitting room, kitchenette, office, one full bathroom and a washer/dryer. The south wing three-car garage is accessed only from exterior doors. Overlooking the bucolic backyard, the primary suite with limestone fireplace and tray ceiling has a charming sitting area, two custom outfitted dressing rooms and two luxurious bathrooms - both with radiant-heated floors. There are four more en-suite bedrooms on this floor. In the southern wing, the largest of the additional bedrooms opens to its own exceptionally large view deck. The northern wing has a second family room and laundry room. A sunny exercise room with large windows and rubber-cork flooring looks out over the tennis court. This floor has a staff suite with kitchenette and full bathroom, as well as a spacious playroom or location for future theater or golf simulator. In a hidden setting on 3.93± tree-ringed acres, the lush backyard is buffered by almost 78 acres of protected land. Resort-like amenities include a pool with pool cabana, Har-Tru tennis court, tennis pavilion and firepit with stone seating. Opening to both the pool and tennis court, the fully enclosed, heated tennis pavilion has a fireplace, wet bar and wine refrigerator. The pool cabana has a changing room, a full bathroom and an outdoor fireplace under a delightful pergola. For gardening enthusiasts, there is a fenced vegetable garden and two fenced berry patches.
