Under contract-accepting backup offers. One or more of these photos were virtually staged. A rare opportunity to create one of the most distinguished residences in Dorado Beach East. Set on an expansive 1,837-square-meter lot with lake views—among the most coveted parcels in the community—406 Dorado Beach East is an existing Casona Carbia 2000 offering approximately 6,000 square feet of interior living space and an exceptional foundation for a transformative estate. Developed architectural plans envision expanding the existing residence into an approximately 12,000-square-foot estate, dramatically increasing both the scale and functionality of the home. The plans illustrate a thoughtful three-level expansion with generous living and dining spaces, a substantial in-law suite, additional bedrooms, a private primary suite, gym, office, cinema, multiple terraces, and a resort-style pool. The proposed first floor alone introduces expansive entertaining areas, an approximately 1,544-square-foot pool, and more than 1,900 square feet of terraces and outdoor living areas. The upper levels further expand the residence with a private primary retreat, additional en-suite bedrooms, a 929-square-foot gym, a 1,550-square-foot terrace and deck, and a third level with a dedicated office, cinema, fourth bedroom and additional terraces. Architectural plans have been approved by the Dorado Beach East Homeowners Association, with approximately 80% of the schematics completed by the architect. Importantly, all major demolition has already been completed, substantially advancing the project and allowing the next owner to continue from an already established stage of development. The result is an unusually compelling opportunity: an exceptional 1,837-square-meter parcel, an existing Casona Carbia, and an advanced architectural vision that expands the residence from approximately 4,407 square feet to a proposed 12,000-square-foot private estate—with the architectural work, approvals, and heavy demolition already substantially underway. A rare opportunity to shape an extraordinary estate in one of Dorado Beach East’s most coveted settings.
