Bal Harbour 101 is a 19-story oceanfront condominium at 10155 Collins Avenue in Bal Harbour Village, completed in 1977 with 172 residences. Bal Harbour 101's floor plans run two-, three-, and four-bedroom layouts ranging from roughly 2,135 to 3,690 interior square feet, plus two penthouses on the 20th floor with private terraces and dedicated rooftop access. The substantial unit footprints give Bal Harbour 101 one of the largest average residence sizes in 1970s-era Bal Harbour, and the building has been steadily owner-renovated over the decades. Many residences have been gutted and rebuilt with porcelain or marble tile, custom open kitchens, quartz or stone counters, integrated modern appliance packages, custom millwork, and updated baths, with direct east-facing Atlantic Ocean views or Intracoastal Waterway exposures from rear-facing lines and corner wraparound balconies in select lines. The 10155 Collins address sits in the center of Bal Harbour Village, directly across the street from Bal Harbour Shops with Hermes, Chanel, Dior, Brunello Cucinelli, Goyard, Saint Laurent, and dining at Le Zoo, Carpaccio, and Makoto, and adjacent to the Sea View Hotel and the Ritz-Carlton Bal Harbour. The Bal Harbour beachwalk runs immediately behind the property, connecting south through Surfside to the Four Seasons Surf Club, the Surf Club Restaurant by Thomas Keller, and Le Sirenuse Miami within a 10-minute walk. Haulover Park, Haulover Marina, and the Haulover tennis center sit five minutes north, with Aventura Mall and the Brightline Aventura station within 15 minutes by car west across the Broad Causeway. The Indian Creek Country Club is a five-minute drive west across the Intracoastal. Bal Harbour 101's amenity program includes an oceanfront heated swimming pool with sundeck and cabanas, a fitness center, a sauna, a clubroom, a billiards room, an on-site convenience operation, and a private boardwalk gate to the beach, with 24-hour security, front desk staff, valet service, and on-site management. The building maintains assigned covered garage parking, guest parking, bicycle storage, package handling, and select pet-friendly policies, with beach chair and umbrella service in season and a landscaped pool deck running along the oceanfront. A renovated lobby and updated common-area corridors put Bal Harbour 101 ahead of most 1970s-era buildings in the village.
