Farm

Set within the rolling hills of Millbrook Hunt Country and framed by sweeping views of the Catskill Mountains, this extraordinary equestrian estate encompasses approximately 185 private acres in one of the Hudson Valley’s most established sporting landscapes. Once the cherished country retreat of Margaret Carnegie, the only child of industrialist and philanthropist Andrew Carnegie, the property carries a distinguished legacy that continues to shape its character today. Originally constructed in 1865, the estate has been thoughtfully expanded and renovated over time, preserving its historic significance while introducing modern comforts and amenities suited to contemporary living.

Spanning more than 13,700 sf across multiple living structures, the estate offers a total of nine bedrooms, nine full baths, and one half bath. At the center of the property is a stone-and-wood residence inspired by Scotland’s famed Skibo Castle. The main residence combines grand entertaining spaces with inviting everyday living areas, including a richly paneled library with a fireplace, a formal dining room capable of hosting up to 30 guests, and a dramatic living room with soaring 20-ft ceilings, a fireplace, and French doors that open to a terrace overlooking the Catskills. A renovated chef’s kitchen features Viking and Bosch appliances, a breakfast room, and spaces designed for both large gatherings and casual family meals. Upstairs, the primary suite includes a sitting room, dressing room, and private bath, while additional suites provide comfortable guest accommodations. Modern enhancements, including an elevator and carefully integrated expansions, complement the residence’s historic architecture.

The estate’s equestrian facilities are equally impressive. Designed by renowned French architectural firm Atelier Choiseul, the world-class equestrian complex includes state-of-the-art stables, a tack room, staff housing, a refined lounge, and meticulously maintained paddocks ranging from six to twelve acres, each enclosed with post-and-rail fencing. Several paddocks include field shelters, while miles of fenced pastureland and private riding trails create an exceptional environment for both horses and riders. A hunter trial course further enhances the property’s appeal to serious equestrians, while two farm-manager apartments, groom accommodations, and extensive utility facilities support daily operations.

Beyond its equestrian amenities, the estate offers a quintessential Hudson Valley landscape of rolling meadows, mature woodlands, tranquil ponds, and carefully maintained grounds. A carriage house provides three additional apartments, storage for five vehicles, and a winter greenhouse, creating flexibility for guests, staff, or extended family. Throughout the property, numerous vantage points—including sunset-facing terraces and a picturesque gazebo—capture the surrounding mountain views and pastoral scenery.

Millbrook has long been regarded as one of the Hudson Valley’s premier equestrian and country destinations. Known for its historic estates, scenic countryside, and enduring sporting traditions, the area is home to the Millbrook Hunt, Mashomack Polo Club, and Sandanona, one of the oldest continuously operating hunt clubs in the United States. Residents enjoy access to riding, polo, hiking, golf, wineries, and outdoor recreation throughout the region, while the Village of Millbrook offers boutique shopping, dining, and everyday conveniences just minutes away. Despite its remarkable privacy and sense of seclusion, the estate remains within approximately 90 minutes of Manhattan, making it well-suited as either a full-time residence or weekend retreat.
