About this home
Extraordinary Compound or Weekend Retreat in Beautiful "LAKE MAHOPAC". This is a rare opportunity to own a truly exceptional estate in "LAKE MAHOPAC"—a magnificent 6-bedroom, 5.5-bath custom-built Colonial with over 6,000 square feet of elegant living space. Set atop a private road at the end of a cul-de-sac, the home is nestled on 3.47 level, beautifully landscaped acres and includes deeded lake rights to a private 100-foot sandy beach and boat dock on the spectacular, motorboat-friendly Lake Mahopac. The moment you enter the grand two-story foyer; you're greeted by a stunning custom staircase and an abundance of natural light. The interior showcases soaring 10-foot ceilings, elegant arched openings, detailed moldings, and inlaid hardwood floors. The gourmet island kitchen is a chef’s dream, featuring a picture window breakfast area, Sub-Zero refrigerator, Wolf stove, wine cooler, and newly added Bosch microwave, Bosch dishwasher, and GE Profile Advantium double wall oven with European convection, air fry, steam bake, and sous vide modes. A second staircase conveniently connects the kitchen to the upper level. The spacious family room includes a floor-to-ceiling stone fireplace, while the large formal dining room and elegant living room provide perfect spaces for entertaining. A private office completes the main floor. Upstairs, the luxurious primary suite is truly one-of-a-kind. It includes tray ceilings, a large separate sitting room with sliding doors to a beautiful cedar three-season room featuring a propane heater. The oversize spa-style primary bath includes a soaking tub, a separate shower and dual sinks. The primary bedroom includes custom his-and-her walk-in closets with built-in Birchwood cabinetry and another stone fireplace. The second floor also offers a Jack and Jill suite, a Princess suite, two additional bedrooms (one with an en suite bath), a full hall bath, and a laundry room with a brand-new washer. The recently completed lower level adds 1,492 square feet of finished space with 9-foot ceilings. It’s divided between a massive recreation/game room with space for a home theater, billiards, ping pong, and more, and a fully equipped "LEGAL ACCESSORY APARTMENT" with its own private entrance, one bedroom, living room, kitchen, and a spa-like full bath with radiant heated floors. This space is ideal for in-laws, an au-pair, extended family, or guests. A full staircase leads to the expansive attic, which is the length of the home and already floored for storage. The oversized three-car garage includes a second staircase down to the lower level for added convenience. The exterior of the home is finished with durable, no-maintenance "Hardiplank" siding. The landscaping is professionally designed with custom lighting, a sprinkler and irrigation system, and a newly redesigned and rebuilt driveway and private road lined with elegant Belgian block. At the entrance, new custom-built stone pillars with dramatic lighting make a stunning first impression. Recent additions include a new central vacuum system, stadium-quality outdoor floodlights, a paved area for winter boat storage, and a brand-new Arctic cedar saltwater hot tub (available for purchase). Home has been wired for portable generator hook-up. The entire home has also been freshly painted and is in pristine, move-in condition. Located just a five-minute walk from the private beach and only an hour from New York City, this remarkable property combines the serenity of lakefront living with the convenience of nearby highways and Metro-North access. Whether you're looking for a spacious compound, an elegant full-time residence, or a luxurious weekend escape, this home offers it all.
