Property Description
Loft 1B The Ansonia Clock Factory 443 12th Street Set within the historic Ansonia Clock Factory,a distinguished early 20th-century Park Slope warehouse thoughtfully converted into cooperative residences, Loft 1B is a striking street-level duplex, meticulously redesigned in 2014 by architect Philippe Baumann. The renovation masterfully balances the building's industrial heritage with the clean, contemporary clarity for which Baumann Architecture is known. Spanning approximately 1,915 square feet across two expansive levels, the residence is defined by its remarkable volume and structural character. A flood of natural light, soaring near triple-height ceilings, exposed brick, and original beam construction create a dramatic interplay between open living areas andA thoughtfully articulated private spaces. Baumann's redesign emphasizes material continuity throughout, with hardwood flooring, steel and wood detailing, and extensive custom storage enhancing both functionality and aesthetic cohesion. Two distinct mezzanine levels further elevate the sense of verticality while offering flexibility for a variety of uses, whether as sleeping quarters, creative studios, or workspaces. The upper level showcases preserved original structural elements, framing a generous eat-in kitchen and dining area unified within one expansive space, stylishly renovated with granite countertops and custom cabinetry, and anchored by soaring columns that lend a striking architectural presence. In a chorus of elevated "floating" interventions, two mezzanine chambers and a full bathroom overlook the main living space. A distinctive system of accordion panels allows for adaptable privacy, elegantly modulating light and sound. Integrated LED lighting throughout enhances both ambiance and functionality. A sculptural steel staircase serves as both centerpiece and connector, linking the upper volumes to a light-filled lower level designed for everyday living. This level offers generous space for lounging, working, and quiet retreat, all beneath impressive ceiling heights (24 feet height) and an abundance of natural light. The primary suite completes the lower level, with integrated large closets, and featuring a glass-tiled en-suite shower room and a full-sized laundry room, set against modern concrete floors that echo the loft's industrial roots. Accessible via elevator, the building's well-maintained communal rooftop offers sweeping views of Manhattan, including a direct sightline to the Statue of Liberty. It is an ideal setting for al fresco dining, sunset gatherings, and Fourth of July fireworks. Located just minutes from Prospect Park, 443 12th Street retains the authentic character of its industrial past, with oversized windows, substantial proportions, and a true loft sensibility. Residents enjoy a professionally managed, pet-friendly cooperative with elevator access and a beautifully maintained shared rooftop, an exceptional extension of the home.
