45 Hitchcock Ln is one of Millbrook, New York’s most iconic and expansive properties, spanning 2,078 acres of pristine farmland, forest, lakes, and rolling hills. Originally assembled in 1889 from five farms, the estate has remained intact and privately held for over a century. Located just 1.5 hours from NYC, it offers rare seclusion, rich history, and exceptional versatility. Two grand residences define the property: a 14,700+ sq ft mansion by James E. Ware and a 10,000 sq ft guest house by Addison Mizner. Historic structures include Bavarian-style gate and bowling houses, a carriage house, stone barns, farmhouses, and a charming cottage. The land features two large private lakes, multiple ponds, and over four road frontages. Still self-sustaining with hay fields supporting cattle, the estate is a legacy property—preserved, versatile, and brimming with potential. | Listed by Heather Croner • William Pitt Sothebys Int Rlty
