Description

Welcome to this handsome circa 1901 brick single-family townhouse on a coveted tree-lined block in the heart of Park Slope. Rich with original character and filled with natural light, this three-story home plus cellar presents a rare opportunity to restore and reimagine a classic Brooklyn townhouse with incredible scale, warmth, and preserved architectural detail. Beyond the stoop, the home unfolds with gracious proportions, soaring ceilings, original wood floors throughout, decorative fireplaces, pocket doors, French doors, intricate moldings, and beautifully preserved millwork. Historic details remain intact across all levels, offering the perfect canvas for a thoughtful renovation or gradual restoration. The garden level features a well proportioned living space and oversized eat-in kitchen with terra-cotta tile floors, tin ceilings, abundant cabinetry, and a bright sunroom overlooking the expansive backyard. A charming full bath and direct garden access complete the level, creating excellent potential for indoor-outdoor living and entertaining. At the rear of the building, a deep private backyard provides an exceptional outdoor retreat rarely found in Park Slope - ideal for gardening, entertaining, or creating a truly spectacular landscaped oasis. The parlor floor, most recently used as two bedrooms, also offers an option for dramatic living and entertaining spaces with elegant decorative fireplaces, oversized windows, and original parquet flooring bathed in natural light. Upstairs is a generously scaled bedroom plus two smaller flexible rooms which could be combined to make a second large bedroom on this floor. Also on the top floor is a generously sized bathroom with a skylight. While the property would benefit from updates and restoration, the home's original craftsmanship, layout, and preserved detail make this a compelling opportunity for buyers seeking authenticity and long-term value. Full of charm, scale, and potential, this is a chance to create a truly special townhouse residence in one of Brooklyn's most sought-after neighborhoods.
637 Baltic Street is unique and desirable with its additional unused buildable square feet. Take advantage of the opportunity to expand with 1,181 SF of additional FAR (buildable square feet)
