Set to 5.66 secluded acres, this iconic estate is a rare offering in Westchester County—melding timeless architectural design, rich provenance, and extraordinary lifestyle amenities in a coveted location just 35 minutes from NYC.
Originally built for Rudolph J. Schaefer of the F. & M. Schaefer Brewing Company, the residence was designed by Royal Barry Wills, a master of New England Colonial Revival architecture.
