111 West 67th Street, 35-DEF

This is result of unprecedented thought, care, and attention to detail, and most of all no expense spared. This stunning 4,300-square-foot apartment is undoubtedly one of the healthiest homes in New York. Three years of planning and construction resulted in this irreplaceable property, which enjoys panoramic 360 views of the Manhattan skyline from its perch high above the Upper West Side and steps from Lincoln Center and Central Park.

The home has a truly unique aesthetic the sought after work of Tony Ingrao, a member of Architectural Digests elite AD 100. Every detail is completely new and thoughtfully considered, from hand-selected wood sycamore, white oak, Douglas fir, and caleidolegno to the cleanest materials and the highest-caliber fixtures and finishes. All paint, finishes, and sealants were strictly vetted for chemicals and additives. A Ketra lighting system modulates light spectrum and brightness according to circadian rhythms; color and scheme can be varied to suit any mood or entertaining theme. The residence is completely hypo-allergenic and features a whole-house humidification system, high-end UV-blocking windows (new entire windows, not film), and an advanced triple-osmosis water-filtration system for perfectly pure showers, baths, and drinking water. The entire home benefits from high-speed Wi-Fi, and every room including the master bath and shower has been outfitted with a discreet speaker system. A Savant whole-house-automation system controls heating, air conditioning, music, lighting, and blinds.

Three apartments were combined seamlessly to create the distinctive floor plan, which offers spectacular living spaces and up to four bedrooms. Entertaining is easy in the central living room, which includes a stainless-steel fireplace and a handsome wet bar with cerused Douglas fir cabinetry, a custom sink, and a Sub-Zero wine cooler. The formal dining area features a strikingly artful light fixture and enjoys stunning views of the skyline and Central Park through walls of windows. Sleek and streamlined, the kitchen exemplifies state-of-the-art style and features exceptional finishes such as heated leathered-stone floors, limestone countertops, Dornbracht fixtures, and tile and plaster walls. Two Wolf ovens, a Sub-Zero refrigerator and freezer, a Gaggenau dishwasher and induction cooktop, and a built-in automatic Italian espresso machine are among the top-tier appliances. An inviting casual dining space with built-in seating and whimsical lighting is tucked into a windowed corner of the kitchen, creating a backdrop of enviable Manhattan vistas. In a thoughtful touch that allows for maximum privacy and convenience, two drop-down electronic dividers separate the kitchen from the living area and the den.

Spanning more than 2,000 square feet, the master suite is a chic and serene oasis with a subdued organic palette, oversized windows affording glorious natural light and expansive views across Central Park, and a wall designed for art or a wide-screen television. The lavish spa-inspired bath includes a stunning walk-in steam shower and jetted soaking tub clad in striking Mediterranean Blue quartzite, a vanity with oversized mirrors and Fantini fixtures, a private water closet, and heated floors and towel racks. The suite also encompasses an oversized walk-in closet with a built-in safe, a custom home gym and yoga room, and a relaxing personal sauna with its own Central Park view.
