One Sotheby’s International Realty has assumed responsibility for sales and marketing of 9900 West, a waterfront condominium development in Bay Harbor Islands. The project, located at 9900 West Bay Harbor Drive along the Indian Creek waterway, is being developed by Horizon Group, a firm based in Brooklyn.
According to a news release, One Sotheby’s will be tasked with selling just over half of the building’s 23 units. Sales for the project were initially launched by Douglas Elliman in 2023. Recently, Serhant replaced Douglas Elliman as the sales team for another boutique development, Opus Coconut Grove.
The 9900 West project is currently about 50 percent presold. 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 amenities such as a 10-slip marina, more than 5,000 square feet of gardens, a rooftop pool deck measuring 9,000 square feet, a fitness center, and a spa. Each condo unit includes between two and four bedrooms and ranges from 1,200 to 3,200 square feet.
This marks Horizon Group’s first project in South Florida. The company is led by David Marom and also has plans for additional developments in the region: Residences at Nomi—a residential community for those aged 55 and older in North Miami—and Casa Verde, a luxury condominium project planned nearby on Bay Harbor Islands.
Bay Harbor Islands continues to see new real estate activity with several other condo projects either planned or under construction. These include Continuum Company’s La Baia development and VDA Origin Miami. Office development is also increasing; last year Landau Properties and Taubco secured 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.
