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. ## Property Details - **Property Type**: Co-op - **Beds**: 3 - **Baths**: 2 - **Rooms**: 5 - **Sqft**: 1,915 sqft - **Stories**: 5 - **Year Built**: 1960 - **Price per Sqft**: $1,097 - **Common Charges**: $1,753 / Monthly - **Listed On**: Apr 22, 2026 - **Days on Market**: 148 Days ### Residence Features - Building Washer Dryer Install Allowed - Common On Floor - Building Barbecue - Building Roof Deck - Private Outdoor Space Under 60 Sqft - Eat-in Kitchen - Granite Counters - High Ceilings - Walk-In Closet(s) - Dishwasher - Concrete ## Estimated Monthly Payment **$12,372 / month**, assuming a 20% down payment ($420,000), a 6.5% interest rate and a 30-year term.

Those are excluded from the benchmark below. ### How this price compares - **Last sold price**: $2,100,000 - **Median sold price**: $1,932,635 - **Difference**: +$167,365 (+8.7%) - **Last sold, $/ft²**: $1,097 - **Comparable sales**: 8 - **Sales from**: September 2024 – June 2026 - **Middle half of those sales**: $1,578,750 – $2,312,500 Based on co-op three-bedroom sales in Park Slope. Square footage is recorded for only 2 of these 8 sales (25%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest. This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Park Slope instead. ### How these sales were negotiated - **Sale-to-list price**: 106% (6 sales) - **Sold below asking**: 0% (6 sales) - **Typical time to find a buyer**: 30 days (8 sales) - **Typical time to close**: 106 days (8 sales) Based on co-op three-bedroom sales in Park Slope with the required listing and closing data. Sample sizes vary by metric. These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure. Sales data through September 2026. Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.
