24 Middagh Street is a rare two-family Brooklyn Heights compound-featuring a fully rebuilt main house, a separate carriage house, and private parking, all centered around a private courtyard. The main house spans approximately 3,357 square feet across four levels, offering 4 bedrooms, 4.5 bathrooms, two offices, a music room, and a playroom. A garden-level extension creates seamless flow between the kitchen, dining, and living spaces, anchored by a sculptural custom staircase by New York Stairs. Bathrooms are finished with arched transitions, handmade tile, and spa-like detailing. The home was completely re-engineered behind its preserved shell, including reinforced structure, steel beams, new roof framing, and a steel portico connecting to the courtyard. The chef's kitchen features custom cabinetry, JennAir refrigerator, Miele induction cooktop, Bosch oven, and Calacatta Viola marble from ABC Stone, with a large island and walk-in pantry designed for entertaining. The lower level has been transformed into a fully usable space with a poured concrete slab and micro-topping finish-ideal for a gym, media room, or storage. A seven-zone HVAC system with Nest integration, ERV ventilation, and airtight construction deliver modern comfort, while all-wood exterior materials and double-hung wood windows preserve the home's character. The courtyard has been thoughtfully designed with driveway access, a handcrafted Alaskan Clear Cedar gate, and integrated drainage tied into the city sewer system. The separate carriage house (approx. 900 sq ft) offers 2 bedrooms, 1.5 bathrooms, a wood-burning fireplace, and its own HVAC-ideal for guests, a studio, or a private office. With 24 feet of width, two distinct dwellings, and private parking, this is a rare opportunity to own a turnkey Brooklyn Heights property that works equally well as a single-family residence, multi-generational home, or income-producing investment
