ONE Sotheby’s International Realty Appointed as Exclusive Sales Partner at 9900 West in Bay Harbor Islands as the Project Completes Top-Off

The Horizon Group, the visionary real estate development firm behind more than 30 notable residential and commercial properties in the greater New York City and Miami areas, has appointed  ONE Sotheby’s International Realty as the exclusive sales and marketing team for 9900 West – a limited collection of 23 exquisitely finished residences with a private marina in the highly coveted Bay Harbor Islands. The partnership follows the building’s top off, a significant construction milestone that positions the property for an anticipated delivery in Summer 2026. Envisioned by Frankel Benayoun Architects, the seven-story waterfront tower is nearly 50% sold and vertical construction is complete–ushering in a new standard of refined island living. Blending the privacy of single-family homes with the effortlessness of boutique condominium living, 9900 West was designed as a serene retreat surrounded by water, nature, and immediate access to Miami’s vibrant cultural and social destinations. “9900 West delivers an exceptional waterfront living experience that fills a meaningful gap in the Bay Harbor Islands market by offering an intimate, design-forward environment in a location with rare privacy and walkability,” said Daniel de la Vega, President of ONE Sotheby’s International Realty. “We are honored to lead sales as this remarkable project moves toward completion and further elevates the evolving luxury landscape of the neighborhood.” Situated along the Indian Creek waterway at 9900 West Bay Harbor Drive, the development features impeccably appointed two- to four-bedroom residences plus a penthouse collection, with fully finished interiors by Craft Studio. Light-filled open floor plans range in size from 1,202 to 3,206 square feet and showcase the highest quality finishes, 9-foot ceilings, floor-to-ceiling windows to maximize panoramic views. Glass-encased terraces overlook the water for a seamless connection to the outdoors. Custom Italkraft kitchens are outfitted with Miele appliances, Taj Mahal quartzite countertops, and wine refrigeration. Primary suites offer generous walk-in closets and spa-inspired bathrooms with elegant oak panel detailing, double showers, and floating double vanities. Select homes showcase private rooftop terraces with summer kitchens. The property embraces the location’s tranquil, natural setting with over 5,000 square feet of tropical gardens and serene water features envisioned by Miami’s celebrated Geomantic Designs. It also includes a 9,000 square foot lushly landscaped rooftop with a Finnish saltwater pool and spa, and a trellis-covered lounge area overlooking the property’s private ten-slip marina and Biscayne Bay. Residents gain access to personalized service and lifestyle amenities including an attended lobby and concierge, state-of-the-art fitness center and wellness spa with sauna and cold plunge, entertainment suite with catering kitchen, children’s playroom, pet-grooming room, electric vehicle charging, and valet. Ideally positioned moments from Bal Harbour, Surfside, and Miami Beach–Bay Harbor Islands remains one of South Florida’s most desirable residential enclaves—offering walkability, A-rated schools, pristine parks, and direct access to world-class shopping, dining, cultural institutions, houses of worship, and white-sand beaches. ONE Sotheby’s International Realty is the exclusive sales and marketing partner for the property. Limited residences remain with prices ranging from $3.2 million to $5.1 million.
