Property Details
Description
Easily converted to three bedrooms and beautifully renovated, this dramatic and spacious two bed, two bath, north and west facing, corner apartment boasts 12-ft-high ceilings and wonderful light from eleven oversized windows. Located in Park Slope's most desirable loft building, the Ansonia Court, formerly the historic Ansonia Clock Company factory, is built around an elegantly landscaped, leafy private courtyard.
The striking loft combines stylish 1881 industrial detail with tasteful modern design. A gracious foyer leads to an expansive living room with exposed brickwork, four large, arched factory windows, artfully designed custom bookshelves and eight cabinets, and soaring wooden, beamed ceilings. The living room is open to a large state of the art kitchen featuring honed Carrera marble counter tops and backsplash, Subzero refrigerator, two Fisher Paykel dishwasher drawers and a Miele five-burner stovetop; plenty of counter and cabinet space along with three sinks and a filtered drinking water tap make this kitchen ideal for entertaining. The large corner master bedroom has five oversized windows, beautiful built-in bookshelves, two large closets, one of which is a custom walk in, and a tastefully renovated bathroom, en suite, with floor to ceiling honed Carrara mosaic tile work. A generous second bedroom has two oversized windows and a wall of closets with built-in shelves and drawers; there's an adjacent full bathroom. In addition, there are a full laundry/mechanicals closet and two more large hall closets.
With a full-time super, package room, and space to park bicycles and strollers, the Ansonia Court is a financially sound, pet friendly co-op located in prime South Slope, three blocks from the F and G trains and two blocks from Prospect Park. Neighborhood highlights include Union Market, Talde, Thistle Hill Tavern, Applewood, Fonda and Lady Bird Bakery.
