One Sotheby’s International Realty has assumed sales and marketing responsibilities for 9900 West, a waterfront condominium development located in Bay Harbor Islands. The Horizon Group, based in Brooklyn, selected the Miami-based brokerage to manage the sale of just over half of the building’s 23 units at 9900 West Bay Harbor Drive, which overlooks the Indian Creek waterway.
Previously, Douglas Elliman had launched sales for the project in 2023. However, Elliman was also recently replaced at another boutique development; Serhant is now handling sales for the planned Opus Coconut Grove project.
The 9900 West development is currently about 50 percent presold. The remaining residences are priced between $3.2 million and $5.1 million. Construction on the seven-story building has reached its highest point and completion is expected next summer.
Designed by Frankel Benayoun Architects, the property features a 10-slip marina, more than 5,000 square feet of gardens, a rooftop pool deck spanning 9,000 square feet, as well as a fitness center and spa. Each condo includes two to four bedrooms and ranges from 1,200 to 3,200 square feet.
This marks Horizon Group’s first project in South Florida under the leadership of David Marom. The company’s future plans in the region include Residences at Nomi—a residential community for people aged 55 and older in North Miami—and Casa Verde, a luxury condominium with 39 units also slated for Bay Harbor Islands.
Bay Harbor Islands continues to see new developments with several condo projects underway or planned such as Continuum Company’s La Baia and VDA Origin Miami. Office construction is also active; last year Landau Properties and Taubco secured a $74 million loan for One Kane Concourse at 9551 East Bay Harbor Drive—a seven-story office building near Terra’s Well office and retail space at 1177 Kane Concourse. Tenants such as Tom Brady’s family office and Dwight Capital have signed leases at these new properties.
