Steeped in history and timeless elegance, this extraordinary circa early 1800s home offers over 7100sf of gracious living on 3+ picturesque acres with lovely views overlooking Glass Lake. Originally known as the Knowlson House - a landmark in the community - this Federal-style farmhouse/manor with Greek Revival influences is a rare offering. With a unique and distinctive history, this remarkable residence showcases stunning original architectural detail, expansive entertaining spaces, and a setting that feels private and inviting. Guests are welcomed through the full-width covered front porch into an impressive entrance foyer introducing the home's scale and character. The spectacular ballroom creates an unforgettable gathering space, while the living and formal dining room showcase exceptional historic charm. The dining room is highlighted by a Swarovski crystal chandelier, and the living and dining rooms feature 9 remarkable hand-painted window panels reminiscent of the Hudson River School. The gourmet kitchen/gathering room with brick fireplace serves as the heart of the home and adjoins a fabulous service kitchen featuring a commercial SS sink and handsome vintage cabinetry. The hot tub room, elevator room, a private bath, and ½ bath complete the 1st level. The 2nd floor offers a large foyer, 8 bedrooms, including 2 suites, an office, a charming skylit garden room with a gorgeous vanity, 5 full baths, a large laundry room, a walk-in storage closet, and a rear staircase. Huge 3rd floor walk-up attic for add'l storage. Hardwood floors extend throughout both levels. Nine fireplaces (non-working but potentially restorable) add further charm. The equally impressive exterior includes a paved circular drive framed by handsome stone pillars, expansive side & rear lawns, covered porches, a patio and gazebo, a garage/barn, the old smokehouse, and ample parking. Huge dry basement. This is a rare offering where history, grandeur, and relaxed country living blend seamlessly.
