This rare, 6.3+ acre lot is an architect , designer, or builders dream opportunity. This spectacular private, historic site encompasses an entire mountainside directly overlooking pristine Tuxedo Lake. The property, original site of the circa 1800s Halsey Estate, features numerous lovely walking and hiking paths bordered by historic, hand hewn stone walls and stone walled garden areas that date back to the 1800's. A small, historic stone gardeners shed is included on a large, flat portion of the property that is within close proximity of the home. This was originally a formal garden area, and is accessed by a stone staircase. This would be an ideal location for a pool, croquet lawn, tennis court, or vegetable/flower garden. One entire side of this area is bordered by a historic stone wall. Located at the highest point of the property, and accessed by a wooded walking trail, sits a lovely Gazebo, with panoramic views of the entire lake and surrounding Ramapo Mountains. This beautiful setting is ideal for al fresco dining, picnicking, barbecuing, or just admiring the spectacular sunsets in the evenings over cocktails. The covered gazebo can seat twelve comfortably.
