11 Gramercy Park South presents a rare opportunity to acquire one of the neighborhood’s grand historic townhouses with the flexibility to create a truly exceptional single-family residence. Spanning five stories and approximately 27 feet wide, the home occupies a coveted position directly on Gramercy Park and includes the rare privilege of access to the private park through the coveted Gramercy Park keys.

Currently configured as three residences, the property offers remarkable scale and versatility for a purchaser seeking to create a substantial single-family mansion. Rich architectural details remain throughout, including soaring ceiling heights, original wood-burning fireplaces, restored hardwood floors, grand proportions, and oversized windows overlooking both Gramercy Park and private garden exposures.

The existing owner’s triplex spans the garden, parlor, and third floors, offering a compelling foundation for a future primary residence. The parlor level is particularly impressive, featuring approximately 14-foot ceilings, dramatic entertaining rooms, original wood-burning fireplaces, and direct park views. Below, the garden level is anchored by an expansive eat-in chef’s kitchen opening to a private patio and garden, creating a seamless connection between indoor and outdoor living.

Above, the upper floors are currently configured as two beautifully restored duplex residences, each offering generous living spaces, multiple bedrooms, and original architectural character. Combined, these floors present an extraordinary opportunity to expand the home into a residence of significant scale while preserving the flexibility of the current configuration.

Opportunities to acquire a townhouse of this width, scale, and provenance on Gramercy Park are exceedingly rare. Whether maintained as an income-producing property, occupied as a multi-generational residence, or transformed into one of Manhattan’s great private homes, 11 Gramercy Park South represents a truly unique offering in one of New York City’s most storied enclaves.
