Old House Lovers: your rare opportunity to own a piece of Hudson Valley history has arrived. Long before Croton-on-Hudson became one of Westchester’s most sought-after river towns, A.P. Gardiner - an early 1900s gentleman from New York City - chose this very hillside for his sprawling country estate. "Hessian Hills" served as a seasonal refuge for the Gardiner family and their guests, especially during the colder months when the long driveway up to their main house proved impassable. Undercliffe Lodge, as this particular cottage later became known, is steeped in local legend and even rumored to have hosted secret Prohibition-era gatherings - a rare survivor of Croton's storied past. Today, the former estate grounds are home to the prestigious Hudson National Golf Course, where Croton Village residents may enjoy access to its scenic trails and recreational benefits. Thoughtfully restored in the modern era, the residence retains its original soul while embracing today’s comforts. A sun-drenched, glass-paned porch leads to a wide 48" Dutch door, opening to a warm, period-authentic living room with stone hearth. The kitchen, designed to echo 1920s style, offers the openness today’s buyers crave and is ideal for both quiet breakfasts and joyful dinners with friends. A beautifully appointed mudroom/laundry room with its own back entrance provide storage and easy access to the driveway and garden. Upstairs, discover three bedrooms and a beautifully updated bath with timeless details. The expansive primary suite offers not only dual closets but a bonus room - perfect for a nursery, home office, or perhaps your future spa bathroom. Newly refinished hardwood floors, custom closet systems, and handcrafted storm windows on the first floor add the finishing touches to this charming residence. Outside, almost half an acre offers endless possibilities: garden, entertain, or simply bask in the surroundings that once drew one of New York’s most notable families. Add in the school bus stop right at your gate and nearby train, river, parks, and charming village shops, and you have the best of every world. Write your next chapter in one of Croton’s most notable homes.
