The Birches is the stone gate house formerly associated with the legendary Castle Rock, the Hudson Valley home of William H. Osborn, and is one of the most admired homes in the Garrison - Cold Spring community. Designed during the Gilded Age by Gothic Revival master architect Ralph Adams Cram, the Birches has a grandeur rarely seen since the Gilded Age. The strength and power of its stone construction and design simply could not be replicated in our time. Soaring twelve-foot ceilings and the grand proportions of the formal rooms call to mind Edith Wharton and Jay Gatsby. The property abuts a pastoral field, protected by a Scenic Hudson conservation easement, that looks up to one of the nearby Appalachian mountains that define the Hudson Highlands region. The location is an easy commute to Midtown Manhattan by way of the Garrison train station, which is less than a mile from the house.
