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.
