Offered for the first time ever, 21 Hawkes Avenue is a one of a kind contemporary residence in the Town of Ossining custom built by its current owner, an accomplished contractor, and designed by architect Jim Picone. Completed in 1983 and thoughtfully improved over the years, the home sits on… Read More a private, wooded 1.5-acre parcel originally acquired in 1980. A winding, tree-lined driveway leads to the residence, which is perfectly positioned atop a gentle rise overlooking beautifully maintained grounds. Defined by dramatic rooflines, soaring ceilings, expansive windows, and striking geometric forms, the home was designed to blur the line between indoors and out while embracing its natural surroundings. Surrounded by mature specimen trees, stone edged gardens, broad lawns, and woodland, the property offers exceptional privacy. A historic stone wall borders a gently flowing creek at the edge of the property, creating a peaceful setting rich with wildlife and seasonal beauty. Stone and timber steps lead to a covered entry and welcoming foyer. Inside, open concept living spaces feature exposed beam ceilings, stained softwood floors, and abundant natural light. A dramatic two-story dining area framed by towering trapezoidal windows serves as the heart of the home. The renovated kitchen features custom light green cabinetry, slate countertops sourced from a Vermont quarry, newer appliances, and a custom breakfast table and island inspired by George Nakashima. Glass doors connect the dining area to the wraparound deck, creating seamless indoor/outdoor living. A spacious living area provides the perfect setting for relaxing or entertaining. The main level also includes a full bath, private office or den with cathedral ceilings and built-ins, pantry, laundry room, and generous storage. A wood-burning stove adds warmth and ambiance during the winter months. The custom staircase rises to a light-filled second floor with vaulted ceilings and clerestory windows. The primary suite offers a renovated bath, ample closet space, and serene views of the surrounding landscape. Two additional bedrooms, each featuring signature trapezoidal windows, share a full bath. Above, a charming loft provides flexible space for play, storage, or a cozy retreat. The lower level includes a spacious one car garage with a 220V/40-amp outlet suitable for a Level II EV charger, ample storage space, as well as a workshop and utility room. A permitted accessory apartment, added in 2000, offers approximately 350 square feet with a private entrance, full kitchen, washer/dryer, radiant floor heat, cooling, and yard views. Ideal for rental income, guests, an au pair, in-laws, or a home office, it adds tremendous flexibility and value. Designed with energy efficiency in mind, the home's southern exposure provides passive solar warmth in winter. Solar panels were installed in 2023, and a whole-house automatic generator was added in 2024. Seven mini-split systems provide efficient heating and cooling throughout. Additional features include central vacuum, a monitored security system, and a woodshed stocked with a two-year supply of split hardwood. Despite its private, retreat-like setting, the home enjoys a convenient Ossining location near Route 9A, Route 134, shopping, schools, and everyday amenities. Croton-Harmon Metro-North Station is approximately ten minutes away, offering express service to Grand Central Terminal in roughly 40-45 minutes. Lovingly maintained by its original owners for more than four decades, 21 Hawkes Avenue presents a rare opportunity to own a thoughtfully designed home where architecture, craftsmanship, and nature exist in perfect harmony.
