Description
Built in 1881 as a Victorian-era brownstone, the home, known as The Block House, was thoroughly remodeled by the esteemed Henry Herts in 1906. Herts expanded the house to five stories and refashioned the facade in limestone adding Beaux Arts and neo-Classical elements. Occupied by many of New York's most notable families, the home has appeared in society pages throughout its history and even hosted the venerable Grace Kelly.
