2128 Ocean Ave

Onyx Square is a nine-story condominium completed in 2016 in South Brooklyn, offering studio, one- and two-bedroom floor plans and select three-bedroom residences. The project presents contemporary finishes throughout residences — engineered oak-style flooring, Calacatta Caesarstone counters, custom cabinetry and high-end stainless-steel appliances — plus bathrooms with heated floors and carefully considered millwork. Typical unit features include recessed lighting, pantry space, washer/dryer hookups and step-out balconies or views onto planted courtyards where applicable. Common areas emphasize hospitality and wellness: a staffed lobby with doorman and seating, multiple indoor amenity rooms for residents, a state-of-the-art fitness center with a separate yoga/meditation studio, a residents’ lounge/entertainment room and a kid’s playroom. Outdoor amenity spaces include a landscaped courtyard, furnished terrace areas with grills and a roof deck or private rooftop options on select units. Building systems include elevators and secure entry; some units are offered with private parking or parking available for purchase. Pet policies and specific service packages are determined by condominium governance. The address places the building within the Midwood–Madison–Sheepshead Bay corridor with B/Q express access offering roughly ten-minute rides to Prospect Park/Park Slope or Coney Island, positioning it for residents who want suburban-scaled streets with fast transit links to broader Brooklyn destinations.
