Measuring 13,119 square feet in total and spanning 37 feet in width, this piece of New York history is awaiting its next chapter. Currently configured as a dream penthouse 2-bedroom, 1.5 bathroom loft with 14-foot pitched ceilings atop six half-floor rental apartments and a gracious ground floor retail space, opportunity exists to expand your residential footprint substantially for trophy use while enjoying income from the remaining units below.
