New York (Upper East Side), NY, 10028 | $9,900,000

A rare contemporary duplex condominium offering four bedrooms, a fifth en-suite staff quarters, and five bathrooms, located along Museum Mile and defined by scale, architectural presence, and an extraordinary private terrace overlooking Madison Avenue.

The home’s most compelling feature is its expansive outdoor space. A remarkably large terrace floats above Madison Avenue. With partial views of Central Park framed by iconic Upper East Side architecture, the terrace comfortably accommodates large-scale gatherings while still feeling private and elevated. In a neighborhood dominated by cooperatives, where meaningful outdoor space is uncommon, this offering is particularly distinctive.

Spanning approximately 4, 333 square feet inclusive of interior and exterior space per the offering plan, the residence was thoughtfully combined and renovated within the last decade. Contemporary designer elements result in a home that feels modern yet grounded in its Upper East Side setting.

An architectural staircase connects the two levels, serving as both sculptural feature and structural anchor. Upstairs, the primary suite faces east and northeast, capturing soft morning light and open sky. Adjacent sits an additional bedroom suite, creating a private upper-level wing. This level also includes a substantial laundry room and a secondary entrance, offering flexibility and discreet access.

Downstairs, two additional bedroom suites enjoy western exposures, with glimpses of Central Park visible through the surrounding pre-war facades. Two of the four principal bedrooms are complemented by private balconies that accommodate seating for quiet moments outdoors. In total, the residence offers three distinct outdoor spaces.

The kitchen was designed in a sleek, closed European style, intentionally separated from formal entertaining areas. The adjacent staff suite, complete with en-suite bath and generous closet space, provides natural flexibility. It may remain as configured, serve as a nursery or home office, or allow for future kitchen expansion.

Oversized windows throughout enhance volume and light. The predominant northeast orientation ensures luminous interiors from sunrise onward, while western exposures add depth later in the day.

30 East 85th Street is a white-glove condominium offering full-service living in the heart of Carnegie Hill. The building features a parking garage and direct access to a private E by Equinox gym, both paid separately. Butterfield Market is conveniently located across the street, and Central Park, the museums of Fifth Avenue, and the cultural institutions of Museum Mile are moments away.

Local Law 11 facade work has been ongoing, with anticipated completion in the first half of 2026. A related assessment is currently in place and is scheduled to conclude in May 2026. Terrace images have been digitally enhanced, as photography was limited due to facade equipment in place at the time of shooting. Square footage is approximate and based on the offering plan. There is a 1% capital contribution tax to be paid by the purchaser.
