An Exceptional Country Estate in Northumberland County. Set on 25 acres of rolling countryside with uninterrupted 360-degree views, this distinguished estate offers a rare balance of architectural refinement and natural beauty, just minutes north of Cobourg and within comfortable reach of Toronto. Thoughtfully designed and built to exacting standards, the 11, 000 sq. ft. residence (7, 500 sq. ft. above grade) blends timeless proportions with modern comfort. The arrival unfolds across manicured grounds featuring orchards, curated stonework, and landscape installations by renowned artisan John Shaw-Rimmington, creating a setting that feels both composed and serene. Expansive stone terraces surround a resort-style pool, ideal for entertaining or quiet retreat. A private trail network winds through the property, leading to a hilltop vantage point with sweeping views toward Lake Ontario. Inside, the home is defined by volume and balance. A dramatic great room with 16-foot ceilings, marble columns, and a statement fireplace anchors the principal living spaces, complemented by more intimate rooms for everyday living. A Downsview-designed chef's kitchen, butler's pantry, and adjoining family room offer a seamless blend of form and function. Seven bedrooms and six baths include a private two-bedroom residence with its own garage-ideal for guests or extended family. The primary suite features a dressing room, spa-inspired ensuite with heated floors. Geothermal heating and cooling, a heated three-car attached garage, a separate two-car garage/workshop, and curated designer finishes complete this quietly exceptional estate-well suited as a refined full-time residence or an elegant country retreat for local, GTA and international buyers seeking privacy, space, and distinction.
