Description
If you're looking for the dream Brooklyn Loft, you may have found it.
Perched above the surrounding brownstones within the historic Ansonia Storage Warehouse, Apartment 4B combines the authenticity of a true Brooklyn loft with open views that stretch across Park Slope rooftops toward New York Harbor and the Statue of Liberty beyond. This is the first true two bedroom apartment to hit the market in the building in 14 years, and the first coveted B-line on record.
This expansive, corner two-bedroom home is rich with original character. Exposed brick walls, soaring 11' ceilings, oversized warehouse windows, concrete beams, original pine floors, and original industrial columns create a sense of scale and authenticity that simply cannot be recreated today. If the warehouse was converted today, a developer would likely have created a three bedroom with this amount of space!
The heart of the home is a sprawling living/dining room that takes full advantage of the scale and scope of the industrial footprint. Framed by oversized arched windows and a dramatic exposed brick wall, the space effortlessly accommodates both living and dining while maintaining the open, airy feel that loft buyers dream of finding.
The chef's kitchen has been thoughtfully integrated into the entertaining space and features custom cabinetry, stone countertops, premium appliances (Sub-zero, JennAir), abundant storage (even room for your cookbooks!), and a generous island that naturally becomes the gathering place for family and friends.
Privately tucked away from the living areas, the primary bedroom offers exceptional built-in storage and sweeping western views of brownstone Brooklyn- all the way to the Statue of Liberty.
The second bedroom enjoys open western views and easily functions as a guest room, home office, library, or a creative's dream home studio. Currently outfitted with fabulous wood desks that hide away clutter while keeping an active workspace, the room is large enough to fit any requirement.
The bathroom is clad in warm stone finishes and has a luxurious steam shower installed, as well as a top-of-the-line Toto Washlet. Located across from the bedrooms, it is also conveniently located for guest use.
A dedicated laundry room with new Miele W/D, custom built-ins, and remarkable storage throughout provide a level of practicality rarely associated with loft living.
Originally constructed as one of Brooklyn's great warehouse buildings, the Ansonia Storage Warehouse remains among Park Slope's most sought-after loft cooperatives. Just moments from Prospect Park, the neighborhood's acclaimed restaurants and cafés, and multiple transportation options, Residence 4B offers the rare opportunity to enjoy authentic loft living without compromise.
Character, scale, light, and views-this is the Brooklyn loft buyers spend years waiting for, so don't miss out!
