Rare opportunity to create the 3600 SF townhouse of your dreams in prime Cobble Hill! This 21' wide brownstone has been wonderfully maintained by the current owners through multiple generations and is now in need of its next cosmetic upgrade. A legal four-unit that sits 21' wide x 42' deep (with a small extension) on four floors, with a 100' deep lot, the possibilities are endless in such a stellar location. Upgrade into a massive one or two-family home for yourself, or do minor cosmetic upgrades and rent it out immediately for a fantastic return. On such a perfect block in Cobble Hill, the possibilities are endless and you can be assured of a fantastic investment today, and well into the future. Situated conveniently between Court and Clinton Streets, you will be surrounded on all sides by award-winning restaurants, artisanal shops and grocers, multiple public schools, pocket pocks, and public transportation. Enjoy Union Market, Carrol and Cobble Hill parks, Sociale Brooklyn, PS 29, Mazzola's bakery, and historic treelined streets right outside your front door. Currently configured with one apartment per floor, the house is also awash in period detail, enjoys great light, a huge private garden, and a clean and dry cellar. The roof was redone just two years ago, and the boiler and hot water heater is also in great condition. The garden level is configured as a large one-bedroom apartment with a kitchen off the yard plus a small extension that is used as a laundry/utility room. Head up the stoop to a dramatic parlor floor with soaring 11' ceiling heights, transom windows, tin ceilings, and plaster moldings, and is currently used as a one-bedroom apartment with a home office. The third and fourth floors are both oversized and light-filled with treetop views, and also used as one-bedroom apartments with an additional home office/nursery opportunity. The house is ready and waiting for the new owner to steward this home into the future as a grand one-family home that could easily accommodate 5 bedrooms, 5 baths, and a magnificent living space on the parlor floor. The uniquely elevated location offers views of lower Manhattan and the skyline from the top floor, offering the perfect backdrop for the enterprising owner desiring a private roofdeck. You can also rent the garden unit and take the upper floors for yourself. If you are an investor looking to put your money into Brooklyn's most coveted neighborhood, keep as a 4-family and rent all four floors OR transform it into a condo where exit prices range between $1700 and $2000 PSF, with the added return of finishing out the cellar and also taking advantage of the additional 600SF or so of FAR that can be added on top OR into the yard. Whichever way you choose to use this home, it is a winning situation with no downside. Properties this wide and conveniently situated are a priceless commodity, as they are just not building them like this anymore. In addition, the house has been very well cared-for over the years and offers a super solid foundation for your dream use. Delivered vacant and shown by appointment only. Take the F/G trains to the Carroll Street station and enjoy a short meander past the low-rise buildings, greenspaces and one-of-kind amenities for which Cobble Hill AND Carroll Gardens have become so beloved. Low taxes of only $8,964 per year are an added bonus.
