About This Property

The Finest Country Estate in Northumberland County. Commanding 24 acres of rolling countryside with sweeping 360-degree views, this estate offers a rare combination of architectural mastery and natural beauty, just minutes north of Cobourg. Built with uncompromising craftsmanship, the 11,000 sq. ft. residence (7,500 sq. ft. above grade) blends timeless elegance with modern refinement. From the moment you arrive, the landscape sets the stage with meticulously groomed lawns, orchards, and stone installations by celebrated artisan John Shaw-Rimmington that create a sculpted canvas for outdoor living. At its heart, a resort-style pool framed by expansive stone terraces invites both grand entertaining and quiet retreat, while a private trail system winds through forested grounds to a hilltop lookout with panoramic views of Lake Ontario. Indoors, the residence impresses with a soaring great room 16-foot ceilings, marble columns, and a dramatic fireplace balanced by intimate spaces for everyday living. A Downsview-designed chefs kitchen, butlers pantry, and family room elevate both function and comfort. Seven bedrooms and six baths include a private 2-bedroom suite with it's own garage, while the primary retreat offers a dressing room, spa-inspired ensuite with heated floors, and sauna. Geothermal heating/cooling, an attached 3 car heated garage, a detached 2 car garage/shop and curated designer finishes complete this one-of-a-kind sanctuary. A true estate where architecture, landscape, and lifestyle converge at the highest level.
