Located at the corner of Clark and Willow Streets - one of Brooklyn Heights' most picturesque residential blocks and surrounded by a richly layered architectural landscape - this beautifully proportioned Classic Six offers a rare combination of scale, light, and striking pre-war character. A formal entry gallery introduces the home, highlighted by seventeen oversized windows and triple exposures. Eastern exposures frame a verdant canopy and the historic townhouses of Willow Street, while southern and western light sweeps across the apartment throughout the day. Rich in original detail and lovingly maintained over the years, the residence retains the character and grace that define the neighborhood's most coveted homes. Soaring ceilings over 9.5 ft, original hardwood floors, substantial moldings, and generously scaled rooms provide an exceptional foundation for its next chapter of thoughtful reinvention. The layout itself is defined by a separation between living and entertaining spaces and the private bedrooms. The living room and formal dining room are generously sized for both everyday living and larger gatherings, while the adjacent kitchen presents an opportunity for customization. Three spacious bedrooms are quietly situated within the private wing of the home, along with two windowed baths and abundant closet storage throughout. The apartment also comes with additional private storage. 15 Clark Street is a well-established, pet friendly elevator cooperative with a resident super, private storage, bike and stroller storage, and additional laundry facilities. Located within Brooklyn Heights' landmark district, it is moments from the Promenade, Brooklyn Bridge Park, neighborhood cafés and restaurants, ferry service, and multiple subway lines. Shown by private appointment.
