Description

Enjoy Park Slope living at its finest in this impressive convertible 3 bedroom, 1.5 bath duplex apartment (see alternate floor plans) with mezzanine space at the highly sought-after Ansonia Court! Impeccably designed and thoughtfully laid out on 2 levels, this home offers gracious lofty living, beautiful volume of space complemented by a prized private patio for your outdoor pleasure. High wood-beam ceilings, rich hardwood floors, tasteful built-ins and gorgeous exposed brick grace the ambiance of this townhouse-like residence, made luminous by oversized industrial-style arched windows.
Upon entering the main level you'll be welcomed by an elegant light-filled west-facing living room with soaring 12'3' ceilings, perfect for relaxing and hosting guests. Glass doors open to a coveted amenity -- a lovely fenced-in patio where you can sip morning coffee or evening cocktails with a backdrop of treetop greenery and grand architecture. The fabulous open kitchen featuring plenty of room for dining is finely appointed with light filtering in from eastern facing windows. New appliances include a Thermador cooktop, oven and microwave combo, both with convection, updated electrical, and a KitchenAid refrigerator and dishwasher for the chef. A convenient upgraded powder room and built-in storage round out the lower floor.
Ascend to the upper story via the newly-carpeted staircase, where the comfort continues with airy 11+' ceilings, a capacious master bedroom gazing onto a tranquil garden oasis, a guest bedroom large enough to potentially transition into two (each bedroom with custom window blinds), a generous full bath, laundry room, and ample closets. Access a cleverly situated mezzanine with its arched window now more than ever perfect for use as a home office, play space or storage.
Live luxuriously in the very handsome, former turn-of-the-century Ansonia Court clock factory building, converted to a cooperative in 1982. A lush landscaped courtyard with flowering trees, benches and fountain provides a retreat for residents, plus there's a full-time super, porter, and bike and stroller storage right outside your door. The exceptional location in the heart of the South Slope is less than 2 blocks from the beauty and activity of prized Prospect Park, and minutes to a myriad of shops and eateries that dot the surrounding avenues. Also nearby is the new Nitehawk Cinema, the YMCA Armory, 9th Street Y, Union Market, plus the F and G trains. The Ansonia is a smoke-free cooperative and pets are allowed. Truly a treasure to call home! Note: any alternate 3 bedroom plan is subject to appropriate approvals.
