A Legacy Estate of Uncommon Distinction — Buttonball Hill
Conceived in 1929 for Vanderbilt heir Aldred Coster Schermerhorn, Buttonball Hill is a masterwork of Georgian architecture set amid sweeping manicured grounds. The classic red brick and clapboard exterior — crowned by a slate roof and crisp black shutters — announces itself with quiet authority.
Inside, a double-height foyer with hand-carved moldings and a gracefully curved staircase sets the tone. Soaring ceilings and a natural flow make the principal rooms equally suited to intimate daily living and grand entertaining. The formal living room opens through French doors into a sun-filled solarium; the chestnut-paneled library and cozy den each offer their own fireplace and garden access.
The chef’s kitchen is a true centerpiece — expansive and impeccably appointed, with top-of-the-line appliances, custom cabinetry, and generous counter space designed for serious cooking and effortless hosting. Multiple seating areas make it the natural heart of the home: a sun-drenched breakfast nook overlooking the gardens, a sprawling island ideal for casual dining, and a comfortable sitting area perfect for gathering with family and guests.
The primary suite is a sanctuary: sitting room, two ensuite baths, fireplace, and a private balcony with sweeping estate views. Outside, a heated pool, Har-Tru tennis court, and beautifully landscaped gardens round out the resort-caliber grounds.
A superbly maintained estate where historic soul meets modern ease — minutes from top schools, village amenities, and convenient rail access to the city.
