Calvin Klein co-founder lists Westchester equestrian estate for $100M

In the city, $100 million buys a ritzy 11,000-square-foot duplex penthouse with Central Park views. An hour north, in Westchester County, that bounty gets a 24,000-square-foot manor on 740 pristine acres used for raising Thoroughbred racehorses that have racked up the highest equestrian accolades.

The estate in discussion is Stonewall Farm, the largest private property in the county, owned and currently listed for that gargantuan sum by Calvin Klein co-founder Barry K. Schwartz. Schwartz purchased the first of the 18 contiguous parcels that make up the estate in 1979, and quickly got to work turning the land into “an equestrian estate of the highest caliber,” per the listing.

The manor house was erected in 2004 with a “colonial plantation-style” design by Rebecca Rasmussen Architects. It’s hard to distill such a colossal personal dwelling into bite-sized snippets, but here are some of the home’s more notable features, many courtesy of interior designer Kelly Hoppen: A slate roof repurposed from Yale Divinity School, a master suite with a Japanese-inspired indoor garden, a two-story library with a fireplace surrounded by saddle leather tiles, a 2,200-bottle wine cellar, and a sunroom with arched glass ceilings that lets out onto a bluestone patio. Another noteworthy inclusion is the property’s 4,000-square-foot pavilion housing a gym, sauna, and 60-foot pool flanked by a grand fireplace.

The meticulously tended grounds designed by vaunted landscape architect Edmund D. Hollander include a French garden with lavender and boxwood hedges, a pergola walkway approaching the indoor pool, and a Japanese garden with a koi pond and a butterfly house. Not least is the property’s 40-stall yearling barn, two 24-stall broodmare barns, round pens, paddocks, and turf racetrack that have housed and honed some of the country’s most prized race horses.
