Description

Only rarely does a townhouse apartment with private terrace become available. A dream of townhouse living has been realized in this triplex apartment architecturally designed by Michael Gabellini. The elevator opens directly into the apartment revealing his minimalist vision of serenity and natural light. The highest craftsmanship has been lavished onto the natural finishes of limestone, Thassos marble, Vermont Bluestone, Jet Mist Granite, and Walnut to create this stunning and comfortable home with knife edge floating walls and glass "so everything connects but nothing touches". The living room has a wall of windows with limestone window bench looking south to one of the city's prettiest, most prestigious townhouse blocks as well as a Bluestone and stainless steel wood-burning fireplace. The living area with continuous Sivic Marble floor and lofty skylight ceiling leads directly to the Bulthaup stainless steel kitchen with Miele appliances, vented Gaggenau stove, floor-to-ceiling French door windows with open north exposure, and walnut pantry. The sleek home office has open north view and generous custom storage. From the living room a circular staircase with floating 18' glass wall leads to the master suite with 8"wide plank walnut floors, south facing windows with limestone window sills and walnut grills overlooking the trees, and a wall of closets includes cantilevered, slant-edge shelves, sliding doors plus a stainless steel framed mirror that moves length of the closets.The master bath is clad in 36x36 limestone slabs, a limestone trough double sink, a Jet Mist granite tub, limestone shower, sliding mirror cabinet with stainless steel framed backing. Skylights bring diffused daylight to the living areas and the floating Walnut staircase with hand-formed solid walnut railing leading up to a loft bedroom and bath that has open north views and generous closets. A private landscaped terrace crowns the home. Miele washer & vented dryer. Central HVAC. Pet friendly. Financing permitted. Pied-a-Terre and International buyers welcome. LLC purchase allowed. The Upper East Side is considered to be New York's finest neighborhood with the East 70's between Fifth and Madison Avenues its most coveted blocks.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
