This Upper West Side townhouse is ready for conversion to single-family use! Currently, the owner lives in the magnificent two-story duplex apartment comprised of the parlor and the third floor and uses the townhouse’s spacious garden level as a business office. The fourth floor is occupied as a luxury rental, providing $4,100 month-to-month. For an owner’s triplex, the garden level can be joined with the duplex. Additionally, the size and ceiling height of the basement allows for the townhouse to be expanded by an additional floor into an owner’s quadraplex.
