One Sotheby’s International Realty has assumed responsibility for sales and marketing of 9900 West, a waterfront condominium project 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 was in charge of sales for the project after launching them in 2023. Recently, Serhant replaced Douglas Elliman as sales agent for another boutique development, Opus Coconut Grove.
The 9900 West project is nearly half presold. The remaining units 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 development features a 10-slip marina, more than 5,000 square feet of gardens, a rooftop pool deck spanning 9,000 square feet, a fitness center, and a 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 firm also plans other developments in the region: Residences at Nomi—a residential community for those aged 55 and older—at 950 Northeast 124th Street in North Miami; and Casa Verde, a luxury condominium with 39 units planned for the site at 1130-1150 93rd Street in Bay Harbor Islands.
Bay Harbor Islands continues to see significant real estate activity with several condo projects underway or planned—including Continuum Company’s La Baia development and VDA Origin Miami—as well as new office buildings being constructed. Last year saw Landau Properties and Taubco secure a $74 million construction loan for One Kane Concourse at 9551 East Bay Harbor Drive. This office building is close to Terra’s Well office and retail complex at 1177 Kane Concourse where Tom Brady’s family office and Dwight Capital have signed leases.
