Dumbarton Oaks Swimming Pool
Historic pool restoration with modern aquatic systems and landscape integration
Project Overview
The Dumbarton Oaks Swimming Pool restoration project represents a careful balance between preserving a historic landmark and implementing modern aquatic facility standards. Originally constructed in the 1930s as part of the estate's recreational facilities, this pool required comprehensive restoration to address structural deterioration while maintaining its historic character.
Landmark Logix led a comprehensive renovation that included complete structural repairs, installation of modern filtration and chemical treatment systems, restoration of historic tilework and coping, and enhanced landscape integration. The project required close coordination with historic preservation specialists to ensure all work met National Park Service standards while delivering a fully functional, safe, and sustainable aquatic facility.
Special attention was given to water efficiency, chemical management, and accessibility improvements. The restored pool now serves as both a functioning amenity for Dumbarton Oaks scholars and a preserved example of 1930s estate architecture, demonstrating that historic preservation and modern functionality can coexist seamlessly.
