Description

Top-floor lofts rarely come to the market in Brooklyn, and this one, in the Ansonia Storage Warehouse, is truly special. Nearly 1,000 square feet of true loft space, completely flexible and entirely your own. Configure it as a two-bedroom or keep it as a grand one-bedroom and let the layout breathe the way it should. Soaring 11' ceilings, original pine floors, exposed brick, and a working wood-burning fireplace give the space genuine warmth and character that's hard to find anywhere in the city at this price, especially in Park Slope. Fun fact: this was the original office of the warehouse, and that's why it has the only WBFP in the building! The renovated kitchen has a new stainless steel Frigedaire appliance package (Stove, Refrigerator, Dishwasher and Microwave) and has plenty of counterspace and cabinets, and an island with bar stools for casual dining. The bathroom is spacious and modern, with a Whirlpool washer/dryer. A skylight above the loft is a rare treasure, bringing in natural light and a uniqueness that will make your friends jealous. Beneath the loft is a huge amount of storage - 360 cubic feet, where you can store off-season clothes, rarely used kitchen appliances, or your accordion. This huge area helps keep the rest of the apartment neat and tidy. You could store 3 entire cords of firewood in here - that's how big it is. The building's rooftop is a special treat, with sweeping views of the Manhattan Skyline and even a direct sightline to the statue of liberty. Being on the top floor allows an owner easy access to the rooftop for al fresco dining, sunset drinks, or just enjoying the view. The Ansonia Storage Warehouse is a landmarked circa-1909 elevator co-op on one of Park Slope's prettiest tree-lined blocks, just over a block from Prospect Park and the Grand Army Plaza Farmers Market. The F/G subway is around the corner. One of a kind. Come see it.
