Description

Set on one of Park Slope's most coveted blocks, Welcome to 405 Third Street, 2. This elegant south-facing two-bedroom, one-bathroom co-op combines classic brownstone character with thoughtful contemporary updates and an unusually generous private terrace.Enter through an original wood door into a gracious parlor defined by soaring 10.5-foot ceilings, beautiful proportions, and abundant southern light. A wood burnining, brick fireplace adds warmth and character, while modern lighting upgrades bring a refined contemporary touch.The open kitchen has been thoughtfully integrated into the living space, with custom cabinetry, quartz countertops, Bosch dishwasher, and modern stainless steel appliances. The existing counter provides seating and can easily be reconfigured without the overhang for those who prefer to create a larger dining area.The brand-new bathroom was just completed, and was finished with timeless marble basketweave tile, a fluted wood vanity, and carefully selected modern fixtures.Both bedrooms offer more than the typical city footprint. The spacious primary bedroom comfortably accommodates a king-size bed with additional seating, while the second bedroom offers considerable floor space beyond a twin bed, making it equally well suited as a bedroom, office, or flexible guest space. An in-unit washer dryer is tucked off the bathroom with an opportunity to combine the laundry area and adjacent hall closet to create a compact walk-in closet or additional storage.The large private terrace, completely redone in 2025 with new ironwork and waterproof decking membrane, offers ample space for outdoor dining, lounging, gardening, and entertaining. If one wishes, there is also room for an AC condenser on the terrace should a future owner choose to pursue central or ductless cooling, subject to building requirements and electrical upgrades.The intimate, self-managed four-unit co-op offers the character and community of a classic brownstone with the simplicity of a small building, with all shareholders serving on the board. Pets are allowed. Recent capital improvements include complete facade and stoop resurfacing in 2023 and a roof repair in 2026, with the roof assessment already paid.Third Street is beloved for its unusually wide, double sidewalks, strong sense of community, and annual block parties. The location places you between JJ Byrne Playground and Prospect Park, with easy access to the R and F trains, the B63, and Atlantic Terminal/Barclays Center. Some of the neighborhood's favorite destinations are just around the corner, including Stone Park, Kings Co Imperial, Emmy Squared, Simple Loaf, Terre, L'Albero dei Gelati, and countless other neighborhood staples.A gracious Park Slope home with light, scale, outdoor space, original character, and thoughtful updates-on a block that feels distinctly like home. Come see for yourself!
