Presenting approximately 40 breathtaking, private and serene acres in the rolling Northumberland Hills! The spectacular, custom-built residence with approximately 3500 sq ft ( of finished living space combined with the walk out lower level ) is designed for elegant living and effortless entertaining. Vaulted ceilings crown the great room, anchored by a striking stone fireplace. A gourmet kitchen opens seamlessly to an expansive dining area, ideal for hosting. The main-floor primary suite features a walk-in closet, spa-inspired ensuite and private balcony capturing spectacular sunrise vistas. A welcoming den, sunroom, and beautifully finished lower level with walkouts provide exceptional space for family, guests, and recreation. A separate bunkie adds flexibility for extended family or guests and a full backup generator provides peace of mind. What truly sets this estate apart is its professional-grade equestrian facility. The modern 8-stall barn includes tack, feed, and storage rooms and connects directly to a bright 6,000 sq ft indoor riding arena with excellent footing and ceiling height. This fully realized private equestrian centre offering panoramic views, refined living, and turnkey infrastructure is rarely found just east of the GTA. The lower acreage is thoughtfully laid out with 7 paddocks, open pasture, woodland riding trails and a bass-stocked pond, creating a private training and lifestyle environment. This offering represents a rare opportunity to acquire a complete equestrian operation within easy reach of the GTA - ideal for the rider, trainer, or investor seeking a turnkey rural enterprise without compromise. A property of this caliber is seldom available in Northumberland County at this affordable price. So many options here, maybe you just want to lease out the equestrian part of the property for income to the professionals and live here comfortably with well over 4 + acres or so surrounding the home at the top of the hill.
