From the curved drive sits "Andorra House", a Colonial Revival estate designed by Robert McGoodwin and nestled amongst the bucolic gardens conceived by the famed Olmstead brothers. Through a courtly front door lays, an inviting center hall with views to the gardens that transitions beautifully to the home's informal and formal spaces and features a sophisticated curvilinear staircase. Thoughtful consideration has kept many original features unique to this home while managing to blend the comfort of modern updates throughout the house. The renovated kitchen offers Viking and Sub-Zero appliances, Carrara marble countertops, and radiant heated slate floors with an attached breakfast room and sizeable butler's pantry, which is perfect for hosting your china and wine collection. Off the kitchen, is an adjoining dining room for large gatherings and features a handsome fireplace. Across the hall, you'll find a family room with built-ins and French doors leading to the covered terrace and connects to a tucked-away study. Completing the first floor is two guest powder rooms and access to the four-car attached garage. Off the second floor landing, is a private master suite, with a sitting room, two fireplaces, and abundant closet space and stars a newly updated en-suite master bath. Two additional guest bedrooms with en-suite and laundry room complete this floor. The third floor has three guest bedrooms, two full guest bathrooms, and a playroom. The home also hosts a private one-bedroom apartment, home gym, and two-story bluestone portico. Conveniently located at the foot of Forbidden Drive and on over 1.6 acres, "Andorra House" is a home for those seeking to live life outdoors.
