This 20’ townhouse sits on a gorgeous Riverside Park block. The brand-new, owner’s south garden triplex is an expansive space with sky-high ceilings and crisp, contemporary finishes. The entire unit was gut renovated in 2011, enlarging the square footage and reinforcing this historic home with steel beam studs designed to last another hundred years. Now this 8-unit townhouse is a turn-key, live-with-income opportunity in a coveted Upper West Side location.
