Zaha Hadid Architects is leading the reconstruction and expansion of Le Schuylkill in Monte Carlo, originally completed in 1963 as Monaco’s first high-rise residential tower. Initiated in January 2024, the project preserves the building’s defining U-shaped plan and strategic orientation toward views of Port Hercule and the Royal Palace, while resolving a steep 22-meter site through dual access from Boulevard de Suisse and Avenue de la Costa. The intervention increases total floor area from 32,000 to 41,000 square meters and establishes a new model for the long-term adaptation of mid-20th-century high-rise buildings in dense urban contexts.

The scheme retains approximately 75 percent of the original concrete structure while upgrading performance through selective demolition, structural reinforcement, and a lightweight low-carbon steel extension at upper levels to meet contemporary seismic and loading requirements. Its environmental strategy combines material reuse, full envelope insulation, high-performance double glazing, and a transition from oil-based systems to renewable energy supported by a seawater circuit, resulting in a projected lifetime carbon impact of 623 kgCO2e per square meter, aligned with the 2030 RIBA Climate Challenge benchmark. A renewed façade composition distinguishes restored and new elements, and all major building systems are comprehensively replaced to current standards. The completed development will include 136 upgraded apartments, six bespoke penthouses, an expanded naturally lit entrance sequence, and new resident amenities including wellness, fitness, and social spaces.
