    What's special

    Welcome to your home in the Park Slope neighborhood of Brooklyn, New York City was built as the Victorian Gothic carriage house of the Maxwell mansion, which was built sometime between 1875 and 1896, and was torn down in 1922. The 25’ ft wide carriage house received a new facade in 1923 designed by Caughey & Evans. The building is one of the few carriage houses in Park Slope; and is a local attraction, which dazzles its passersby. It is located in the Park Slope Historic District (minutes from the park). This awe-inspiring magnificent architectural masterpiece is majestically steeped in exquisite original word work & finely crafted detail throughout (mantle fireplaces, built-in China cabinets, parquet floors, stained glass, towering, tall ceilings, and more). Currently configured as a two-family residence with 3 ensuite bedrooms, formal living, formal dining room & kitchen for each unit- or perfectly ideal as a conversion to the ultimately sublime single-family mansion. This stunning and ultra-unique property is a must see to believe and appreciate. Profound possibilities and potential await with this work of art piece of landmarked real estate gold. Situated in the heart of prime Park Slope- surrounded by the most exciting and essential amenities of Brooklyn’s most desirable & sought-after neighborhoods. An absolutely outstanding opportunity to own a once-in-a-lifetime historic home that will be become your legacy.
