Belle Plaza
Belle Plaza is a 15-story bayfront condominium at 20 Island Avenue on Belle Isle, the easternmost of Miami Beach's Venetian Islands, completed in 1962 and comprising 226 residences. The building was designed by the South Florida architecture firm T. Trip Russell & Associates (later The Russell Partnership), reflecting the mid-century modern character common to Biscayne Bay towers of its era. Residents have access to a heated bayside pool with sundeck, jacuzzi, fitness center, tennis court, barbecue area, resident lounge, bike storage, boat dock, and assigned parking, along with 24-hour concierge/security and valet service. The building sits directly across from Belle Isle Park and The Standard Spa hotel, with easy access to the dining, shopping, and entertainment of Sunset Harbour just across the water. Its Venetian Islands location offers a quieter, more residential counterpoint to South Beach while remaining minutes from downtown Miami.
