9900 West is a boutique eight-story waterfront residence at 9900 West Bay Harbor Drive in Bay Harbor Islands, developed by The Horizon Group with architecture by Frankel Benayoun Architects and Q3 2026 delivery. The 9900 West building delivers a limited collection of 23 residences plus four penthouses in two-, three-, and four-bedroom layouts ranging from approximately 1,202 to 3,206 square feet, with select homes adding dens or home office space. Residences at 9900 West feature 10-foot ceilings, floor-to-ceiling glass, custom Italian kitchens, Sub-Zero and Wolf appliances, Italian stone baths, and oversized private terraces overlooking the Indian Creek waterway. The 9900 West at 9900 W Bay Harbor Drive includes a private 10-slip marina with no fixed bridges between the building and Biscayne Bay or the Atlantic Ocean, giving boat owners direct ocean access from their slip. Bay Harbor Islands is a two-island municipality with single-family homes, low-rise condominiums, and the Kane Concourse retail and dining corridor. The 9900 West site sits on the West Island with Indian Creek frontage facing Indian Creek Country Club and the homes of Indian Creek Village across the water. Bal Harbour Shops, the highest-grossing U.S. retail destination by sales per square foot with Saks, Neiman Marcus, Hermes, and Chanel, sits five minutes east across the Broad Causeway. The K-8 Ruth K. Broad Bay Harbor Elementary School is two blocks away and consistently ranks among Miami-Dade's top public schools. Surfside, Bal Harbour Beach, and the Carl Fisher beachfront homes are five minutes by car. Compared to the high-rise wall of Sunny Isles to the north, Bay Harbor Islands offers a low-density, school-driven, single-family rhythm with the Indian Creek waterway as the building's de facto front yard. The 9900 West amenity program is built around the rooftop and the private marina. Residents at 9900 West share a 9,000-square-foot rooftop deck with a Finnish overflow saltwater pool and spa, trellis-covered lounge areas, a summer kitchen, and panoramic views to Indian Creek and the ocean. The Bay Harbor Islands 9900 West building also offers a state-of-the-art fitness center and spa, a custom wellness package, a private entertainment suite with dining and catering facilities, a children's playroom, a dog grooming room, dockside pick-up and drop-off, and a beach club membership. The 9900 West condominium provides 24-hour concierge, valet, and security, plus assigned covered parking and electric vehicle charging. The private 10-slip marina at 9900 West offers direct boat access to Biscayne Bay and the Atlantic Ocean with no fixed-bridge limitations, making it one of the rare new condominium projects in greater Miami with that capability.
