The Monaco UBS project, completed in 2024, represents a harmonious fusion of historical preservation and contemporary design. Renowned French architect Jean Nouvel was commissioned to reimagine Villa Belgica, a building dating back to the early 20th century, as the new headquarters for UBS Monaco. The project aimed to revitalise the existing structure while introducing modern elements to meet the bank’s evolving needs.

Villa Belgica, located at 2 Avenue de Grande Bretagne, has been a significant landmark in Monaco since its acquisition by Alfred Bouvier in 1925. Over the decades, the building underwent several modifications, including elevations in the early 1930s and between 1956 and 1959, which altered its original appearance. Jean Nouvel’s intervention in 2024 sought to preserve the building’s historical essence while integrating contemporary design elements.
Nouvel’s design approach was to create a “monolithic and monochrome” architecture, blending opaque, matte, and translucent surfaces. This strategy harmonised the building’s past with its present, avoiding a forced elevation. He emphasised that the architecture should express the differences linked to usage and lived histories, incorporating elements like the preserved cornice and reused bow-windows from the previous century.

The building’s façade is a standout feature, consisting of two superimposed stained glass planes that interact with the Mediterranean light. This design gives the tower a translucent appearance, with reflections that change throughout the day. The façade comprises a high-performance thermal layer and a second skin of extra-clear glass, screen-printed with vertical patterns. Between these layers, a 200 mm air gap enhances the depth and energy efficiency of the building.
The upper levels of the Monaco UBS building are designed to enhance the client experience. These floors feature a restaurant, lounge, and a landscaped rooftop offering panoramic views of the sea and the Principality. This integration of leisure spaces within a financial institution reflects a modern approach to banking environments, aiming to provide a comfortable and engaging atmosphere for clients and staff alike.

Sustainability was a key consideration in the project’s design. UBS Monaco aimed to achieve BREEAM Excellent and BD2M ‘Gold’ certifications for the building, reflecting high standards in energy efficiency and environmental responsibility. These certifications demonstrate the bank’s commitment to sustainable development and its dedication to environmental stewardship.
The collaboration between UBS Monaco and Jean Nouvel exemplifies a successful integration of historical architecture with modern design principles. By preserving the building’s historical features while introducing contemporary elements, the project honours the past and embraces the future. This approach sets a precedent for future developments in Monaco’s architectural landscape, showcasing how heritage and innovation can coexist harmoniously.
The Monaco UBS project also highlights the importance of thoughtful urban planning. Situated in the heart of Monaco, the building’s design respects the dense urban context while introducing a translucent volume that stands out without overwhelming its surroundings. This balance between integration and distinction demonstrates a sensitive approach to urban development, considering both the building’s impact on the cityscape and its relationship with the environment.
In conclusion, the Monaco UBS project is a testament to the successful collaboration between a financial institution and a visionary architect. Through careful design and attention to detail, the project revitalises a historic building, creating a modern and sustainable headquarters that serves as a benchmark for future architectural endeavours in Monaco. The integration of leisure spaces within a financial institution reflects a modern approach to banking environments, aiming to provide a comfortable and engaging atmosphere for clients and staff alike.
