Description

1261 Madison Avenue, Apartment 6S Occupying the sixth floor of one of Carnegie Hill's most distinguished landmark buildings, Apartment 6S is a gracious four-bedroom residence defined by exceptional scale, elegant proportions, and an abundance of natural light. Extending along the building's Madison Avenue frontage and wrapping the corner onto East 90th Street, the home enjoys multiple exposures, oversized windows, and a wraparound Juliet balcony, creating a rare sense of openness and bringing expansive views and light into the principal living spaces. Ten-foot ceilings further accentuate the apartment's impressive volume and beautifully proportioned rooms. One enters through a windowed vestibule that opens into an impressive succession of formal living and dining rooms, creating a gracious sense of arrival and a natural flow throughout the home. Elegant cased pocket doors connect the principal living spaces, allowing them to open seamlessly into one expansive entertaining area or be closed off to create more intimate settings. Generously proportioned and thoughtfully arranged, the rooms offer exceptional flexibility for both grand-scale entertaining and comfortable everyday living. The south-facing primary bedroom is a bright and generously proportioned retreat, with excellent closet space and a private en-suite bathroom. The three additional bedrooms are also well sized, each offering ample storage and the flexibility to accommodate bedrooms, guests, or a home office. Two additional bathrooms serve the secondary bedrooms and living spaces. The windowed eat-in kitchen is thoughtfully proportioned for both everyday use and casual dining, with abundant cabinetry, generous counter space, and room for a proper breakfast or dining table. Its practical layout provides ample workspace while maintaining a comfortable connection to the rest of the home. Built at the turn of the century, 1261 Madison Avenue is an intimate, pet-friendly cooperative with just fourteen residences across seven stories. The building is maintained by a dedicated live-in Superintendent and offers a laundry room and bicycle room. The sale of Apartment 6S also includes a private storage room in the basement. The Building 1261 Madison Avenue dates to the formative years of Carnegie Hill. Designed by Buchman & Fox in the French Beaux-Arts style, the building was completed in 1901, during the period when Andrew Carnegie and other prominent New York families were establishing the neighborhood as one of the city's most prestigious residential enclaves. The building was notably advanced for its time, with original amenities including telephones in every apartment, two elevators, built-in steel safes, and two refrigerators per residence. Its architectural significance was formally recognized in 1974, when 1261 Madison Avenue was designated a New York City landmark. Today, 1261 Madison Avenue remains distinguished by its beautiful period architecture, including its tiled mansard roof, rusticated limestone base, and grand entrance. With just fourteen residences, the building offers an intimate and private setting in the heart of Carnegie Hill, moments from Central Park, the Reservoir, and the neighborhood's renowned restaurants, cafés, and boutiques. 2% flip tax paid by the purchaser.
