Description

419 18th Street Offers the Space, Flexibility, and Charm You’ve Been Looking For in a Park Slope Home! A sweet front yard welcomes you into this charming legal two-family home, currently configured as a one-family residence. The home offers three bedrooms, two full bathrooms, an additional flexible room off the kitchen that can serve as a home office or bedroom, and a wonderfully deep backyard. The main level features an inviting open-concept living and dining area that flows into a generous eat-in kitchen. Off the kitchen is additional office space and a full bathroom, with access to the 31-foot backyard—perfect for entertaining, gardening, or simply enjoying your own private outdoor retreat! Upstairs, you’ll find three well-proportioned bedrooms and a second full bathroom. A side yard provides a coveted third exposure, bringing additional natural light into the home while also offering a convenient secondary entrance from the street to the rear of the property. The possibilities continue downstairs. The basement is currently configured with laundry and offers approximately 500 additional square feet with seven-foot ceilings. There is ample opportunity to finish this space and create a home gym, recreation room, wine cellar, studio, or whatever best complements your lifestyle. The Home Also Offers An Incredible Opportunity to Customize and Maximize the Existing Space... An alternate floor plan illustrates the potential to open up the kitchen and living areas for an even more expansive and seamless main-level layout. Above, the standup attic provides approximately 270 additional square feet, with a window and beautiful vaulted ceilings. With the possibility of incorporating the attic into the second floor, you could create a dramatic living space with ceilings reaching up to 15 feet! (Please verify all plans, proposed work, dimensions, conditions, and applicable requirements independently with your architect and other appropriate professionals.) With recent updates, including an updated roof, new boiler, and new hot water heater, the house is ready to welcome you in now. You can settle in, enjoy the home as it is, and take your time deciding what you’d like to change down the road. There is also plenty of opportunity to make it your own from the beginning. Either way, the house gives you the freedom to live in it, learn what works for you, and gradually shape it around your lifestyle, your taste, and the way you envision living here for years to come. 18th Street is a quiet, tree-lined block that captures the best of South Slope charm—peaceful, community-oriented, and close to everything. The home is conveniently located near the F, G, and R subway lines, multiple bus routes and Citi Bike stations. Enjoy the Butterfly Gardens just down the block, or take a short stroll to Prospect Park and Greenwood Cemetery. The Greenmarket at Bartel-Pritchard Square takes place every Wednesday year-round, while P.S. 10 is just around the corner! With an array of local cafés, restaurants, and neighborhood favorites nearby, plus the added convenience of Ample Street Parking, 419 18th Street offers space, potential, and classic South Slope appeal. All of this, combined with an attractive price point, makes 419 18th Street a wonderful opportunity to create your dream home in one of Brooklyn’s most beloved neighborhoods! A HOME TO CALL YOUR OWN!
