ONE Sotheby’s International Realty has been appointed as the exclusive sales and marketing team for 9900 West, a 7-story waterfront residential development at 9900 West Bay Harbor Drive in Bay Harbor Islands. The announcement follows the tower’s recent topping off by The Horizon Group, which is overseeing the project’s construction toward an anticipated completion in Summer 2026. Frankel Benayoun Architects is the designer of the 23 unit property and Amana Construction Group is the general contractor.

Vertical construction has reached full height and the structure is now nearly 50 percent sold. The building has been conceived as a low density residential offering with private marina access and a boutique scale layout. Residences range from two to four bedrooms plus a penthouse collection, with interiors fully finished by Craft Studio.
