Property Description for 420 12th Street, F-3L

Welcome home to this extremely special 3 bedroom 2.5-bath duplex in the coveted Ansonia Court. Historic charm mixed with modern amenities invite you into an urban-chic haven, a calm refuge from the city outside. This home feels more like a townhouse than a co-op with soaring rustic beamed ceilings, exposed industrial brick, and oversized arched windows that flood the home with natural light.

Step into a sprawling living area, an oasis with hardwood floors and towering ceilings. Walk right by the carefully hidden in-unit washer /dryer into an expansive and sun-filled open kitchen/dining room with oversized South-facing windows. Off of the kitchen on the first floor is a powder room with serene spa sensibilities. An extra large walk-in closet is hidden under the wooden staircase for additional storage. Up the stairway awaits your dream primary bedroom, with extra large in-suite bathroom, tiled shower and hand-built cabinetry. Two more generous-sized bedrooms share another full bathroom with a vintage double wall-mount sink. Each room has been thoughtfully redesigned and updated for modern living and comfort. This unit comes with roof rights.

Tucked away through the courtyard is the private entrance to building F. It is surrounded by a lush lawn, a fountain, benches and ideal landscaping that all provide a peaceful retreat and common area for all residents to use.

The Ansonia is a well-maintained pet-friendly building with a full-time super, package room. Located just two blocks from Prospect Park and just a few blocks to the 7th Ave F and G train. Neighborhood favorites include Winner bakery, Brook Vin, Cafe Azul, Fonda, Bacaccia, Pasta Louise, Union Market, and local retail shops like Sterling. Located in District 15.

The Ansonia Clock Factory, originally constructed in 1881 closed its doors in the late 1920's.The site was converted in 1982 into "Ansonia Court," a residential co-op, preserving its industrial architecture.

Park Slope | Brooklyn

Quick Profile

Boasting beautiful tree-lined streets, brownstones and a range of activities for all age groups, Park Slope is consistently ranked as one of New York’s most desirable neighborhoods. Filled with lush parks and greenery, the neighborhood is also known for its rare combination of excellent public schools, award-winning restaurants, nightlife, small independently owned businesses and community gardens.

Situated at the western slope of Prospect Park, the neighborhood is divided into different sections: North Slope, Center Slope and South Slope. Depending on who you ask, of course, the definitions of where these borders end and begin may vary (is the divide between North and Center deemed Union Street, Garfield Place, 1st Street or 3rd Street? The one between Center and South 6th Street, 9th Street, 11th Street or 15th Street?). 

Regardless of what part of the Slope you find yourself on, there’s no shortage of architectural beauty. From row houses to brownstones to mansions, the idyllic setting of the neighborhood is further enhanced by its Romanesque and Renaissance Revival styles. Case in point of this is also two of the area’s most well-known churches, Park Slope United Methodist Church and Saint Augustine Roman Catholic Church. 

Revered for its family-friendly appeal, Park Slope is often regarded as one of the best places to raise a family in New York City. That said, it doesn’t mean that parents don’t know how to have a good time... a slew of bars constantly opening in the neighborhood ranging from the high-end cocktail saloon to the dive (well, by Park Slope standards, anyway).
