Located on one of Park Slope’s most coveted park blocks, 602 5th Street is a gracious 20-foot-wide townhouse offering beautiful original details, generous proportions, and a flexible layout just moments from Prospect Park. Currently configured as an expansive upper triplex over a one-bedroom garden apartment, the home offers the opportunity to enjoy substantial living space while maintaining a separate apartment for rental income, guests, or extended family. The upper triplex is distinguished by an elegant center staircase, a layout that creates a wonderful sense of scale and flow throughout the house. The parlor floor retains an exceptional collection of original details, including inlaid parquet floors, stained glass, intricate woodwork, pocket doors, and a handsome pier mirror. Generously proportioned rooms provide multiple options for living, dining, and entertaining. At the rear of the parlor floor, the kitchen features abundant cabinetry and storage, a six-burner BlueStar range, and a gas fireplace. Beyond the kitchen, a sun-filled solarium with walls of windows overlooks the garden and opens onto a deck, creating a seamless connection between the interior and outdoor spaces. The bedroom floors above offer four spacious bedrooms plus additional flexible space for a home office, dressing room, or den. Throughout the house, original fireplaces, stained glass, built-ins, and other period details speak to the craftsmanship and character of this classic Park Slope home. The separate one-bedroom garden apartment provides valuable flexibility and income potential, making the property equally appealing to an end user looking for additional income or someone seeking space for guests or extended family. Perhaps most special is the location. 602 5th Street sits just off Prospect Park West, placing Prospect Park practically at your doorstep while keeping you in the heart of Park Slope. The neighborhood’s restaurants, cafés, shops, farmers market, and transportation are all close at hand. With its 20-foot width, center-stair configuration, beautiful original details, flexible two-unit layout, and exceptional park-block setting, 602 5th Street presents a rare opportunity to create a truly special Park Slope home.
