QEA advanced the stewardship of this historic two-story mansion through a comprehensive modernization.

 
Built in 1932 and modeled on the Parisian Hotel de Rothelin-Charolais, this majestic property overlooking the Potomac River serves as a diplomatic residence and host to distinguished visitors. The project restored ornate 18th century French classical revival details, finishes, and fixtures while integrating state-of-the-art engineering systems and modern conveniences into the historic architecture.

Managing Interventions to Maintain Integrity

The team was committed to retaining the building’s original appearance while modernizing it for stately living and entertaining. Throughout, the character of the original home was retained and enhanced. Original fixtures in the bathrooms were expertly restored. Exterior cleaning of the masonry retain the historic patina of the limestone.  
 
The project reflects many of Belgium’s strict laws regulating eco-friendly construction. All new systems, including air-conditioning and heating systems are energy efficient and are seamlessly and invisibly incorporated into the historic fabric. The numerous original French doors on the exterior, made of cypress wood, were fitted with insulated glazing units and meticulously restored.
