ONE Sotheby’s International Realty will serve as the exclusive sales and marketing team for 9900 West, a collection of 23 luxury condos in Bay Harbor Islands from The Horizon Group.

Vertical construction of the seven-story development recently wrapped up, with completion expected by summer 2026.

The tower is nearly 50% sold. Remaining residences range in price from $3.2 million to $5.1 million.

“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 ONE Sotheby’s International Realty President Daniel de la Vega in a press release. “We are honored to lead sales as this remarkable project moves toward completion and further elevates the evolving luxury landscape of the neighborhood.”
