Overview of Onyx Square at 2128 Ocean Avenue

Completed in 2019, the Onyx Square condominium at 2128 Ocean Avenue in Midwood has set its sights on a new level of sophistication in a neighborhood known for luxury as well as respite from the soaring rents and home prices in nearby neighborhoods. The nine-story, 56-unit, full-service building’s developers emphasized design as well as carefully considered common spaces, and amenities are head and shoulders above most of the neighborhood’s residential offerings, with four indoor and two outdoor amenity spaces. Residential perks include a doorman, a state-of-the-art fitness center, kids’ playroom, landscaped courtyard, bike room, lounge, entertainment room, outdoor entertainment spaces and terraces and on-site parking. The Midwood-Madison-Sheepshead Bay area is considered by some to be one of the city’s best-kept secrets, and the nearby B/Q subways make neighborhoods in either direction–including the Coney Island Boardwalk–just minutes away.
