On a pin-drop quiet, tree-lined block just off Fifth Avenue, 18 East 80th Street is a 25-foot-wide limestone townhouse of exceptional scale and pedigree. Spanning over 14,000 square feet across six levels, the residence has undergone a no-expense-spared gut renovation, delivering a turnkey home that seamlessly blends classic Upper East Side architecture with modern systems. The striking limestone faade sets the tone, while inside, the home offers impressive volume, clean architectural lines, and a layout designed for both formal entertaining and daily living. The entry level is anchored by a showpiece kitchen by Achille Salvagni’s atelier, a $1M+ installation that elevates the space into functional art. Sculpted Calacatta Paonazza marble, custom cabinetry, and integrated appliances are paired with a dramatic island and bespoke detailing throughout. Floor-to-ceiling glass doors open directly to a landscaped garden, creating a seamless indoor-outdoor connection. The parlor level features expansive living and dining rooms with soaring ceilings, fireplaces, and refined proportions. The full-floor primary suite includes a fireplace, dressing room, spa-quality bath, and an adjacent library or sitting room. Two upper floors provide multiple bedrooms with en-suite baths, along with a flexible living space currently used as a grand billiards and entertaining space. The top level is designed for recreation and entertaining, featuring a golf simulator, an adjacent kitchenette, and direct access to a private sun deck. The lower level is fully built out for wellness and service, featuring a large private gym, steam room, sauna, and an expansive laundry and service area. Multiple outdoor spaces extend the living experience, including the garden and elevated terraces. The home benefits from fully upgraded infrastructure, including new HVAC, roof, commercial-grade speed elevator, faade, flooring, and mechanical systems, along with a Lutron-integrated lighting and AV system. Architecture by Tsao & McKown Architects complements the interiors with a cohesive and highly considered design language throughout. A rare combination of width, scale, location, and finish, 18 East 80th Street represents a top-tier Upper East Side offering moments from Central Park.
