443 12Th St

The Ansonia Storage Warehouse at 443 12th Street is a landmarked brick-and-beam co-op in Park Slope converted from an early 20th-century industrial warehouse. The property rises five stories and contains a small collection of roughly three dozen residences, primarily two- and three-bedroom loft-style units characterized by high beamed ceilings (often 11–13 feet), expansive windows, exposed brick walls, original timber columns, and hardwood plank floors. Interiors typically pair industrial bones with modern upgrades: chef-style kitchens with stone or granite counters, updated baths, abundant custom closets and built-in storage, and in-unit washer/dryer hookups in many residences. Common areas are modest but functional — a furnished, planted rooftop deck with communal grills and skyline views is the signature shared amenity, and the building offers elevator service, gated entrance, and professional management. The co-op maintains pet-friendly policies with board approval and generally low monthly maintenance fees. Located on a tree-lined block a short walk from Prospect Park and convenient to F/G subway service, the building sits within a lively neighborhood of restaurants, shops, and schools that supports an urban, family-friendly lifestyle with strong neighborhood character.
