Description

Secluded, sustainable retreat just minutes from downtown Mt. Kisco with Bedford schools and Chappaqua express train commute. Built on an historic 1880’s summer estate, this home offers a rare combination of tranquility, modern efficiency, timeless charm and one level-living. Situated on 1.16 private acres, this home emphasizes sustainability with zero carbon emissions via solar panels, geothermal HVAC, high-performance steel roof and sustainably sourced finishes. The extensively renovated 3700 + sq ft residence offers 3 en-suite bedrooms plus an office (lives like a 4th), 5 baths (3 full, 2 half), plus a multi-use outbuilding perfect for gym, studio or extra office space. Relax by any of the four working fireplaces or amongst the lush gardens and mature plantings on spectacular grounds. The double entry doors open to a stunning, multi-use great room perfect for dining, entertaining, or simply winding down. The reclaimed hemlock plank floors, 12’ ceilings finished in red cedar shiplap, and flagstone-hearth fireplace define an inviting and enchanting gathering space. A wall of French doors bathed in afternoon sunlight lead to the large stone patio, establishing the graceful flow of this unique home. Adjoining the great room, the updated eat-in chef’s kitchen boasts cherry cabinets, an induction cooktop and double convection ovens with a separate entry to the stone patio. It flows to the laundry room, lit by remote-controlled skylights and leads to a split-level wing. A half-flight of stairs leads up to a large, modern loft, a bonus room complete with cork flooring, south-facing French doors, and a soapstone wood stove. Down a half-flight is the insulated three-car garage with ample storage, a pantry, and room for a wine cellar, designed to access the kitchen. Also adjoining the great room, the additional office with fireplace allows work from home comfort, along with its own private 1/2 bath. The main floor primary suite is the perfect blend of old world meets new, with original fir flooring, working fireplace, cedar-lined walk-in closet, and a spa-like renovated bath with radiant floor heating and other modern amenities. Two other main floor en-suite bedrooms complete the floor plan, with one functioning as a legalized apartment with separate entrance allowing for flexible use and income potential. This rare, private and thoughtful retreat blends historic craftsmanship and modern green living conveniently close to town, shops, Leonard Park and transportation. A unique combination not to be missed!
