The remaining residences at the Melo Group's 53-story Aria on the Bay include a range of one- to four-bedroom units priced from the $400,000s to $1.8 million. The tower’s prime bayfront location will provide residences with unobstructed views of Biscayne Bay, Miami Beach and the city skyline.

All four of the building's triplex penthouse residences are spoken for, in prices ranging from $1.8 to over $6 million. They span the building’s top three stories and feature interior living areas measuring from 2,600 to 4,800 square feet in size. The expansive residences offer secluded rooftop terraces with private pools, open-air summer kitchens and 12-foot-deep wraparound balconies that provide up to 3,000 square feet of additional outdoor living space. Features include two private elevators, 10-foot-high floor-to-ceiling glass windows and doors, designer finishes and fixtures, and up to three garage-secured parking spaces.

Building amenities at the Arquitectonica-designed tower include a 14th floor resort amenity deck with two sunrise/sunset-facing swimming pools, a jacuzzi, custom-seated fire pits, barbecue grills and outdoor summer kitchens. Additional perks include a private spa with massage treatment rooms, a state-of-the-art fitness center, yoga studio, indoor/outdoor bar and entertainment lounge, theater-style screening room, game room and library, teen lounge and kid’s playroom, and a business center with offices and meeting facilities. The project also offers 10,000 square feet of available commercial space on the lower floors, including office, retail and restaurant space at the ground level.

Aria on the Bay is situated in the heart of Miami’s Arts & Entertainment District surrounded by the city’s top destinations for world-class dining, arts and culture, shopping, nightlife and entertainment. Situated directly along Biscayne Bay, the 8-acre, pet-friendly waterfront park offers jogging paths, biking trails, tennis courts, basketball courts, soccer fields, an outdoor gym, daily yoga and fitness classes, as well as barbecue areas, picnic and playground areas.
