Extension of The Fondation Maeght

The extension of the Fondation Maeght in Saint-Paul-de-Vence (South of France) expands the exhibition areas by 580 m², respecting the 1960s architecture of Josep Lluís Sert. Conceived as a discreet intervention, it gradually reveals itself along the visitor’s path. Two new volumes, nestled beneath the outdoor Miró and Giacometti courtyards, open through generous frames to the pine forest, creating a dialogue with nature. The framed views guide visitors towards the outdoor Miró Labyrinth, while the nuanced tones and textures of the concrete ensure harmony with the existing building.

The client required a careful balance: preserving the integrity of the 20th-century architecture while giving the extension a contemporary identity. The main challenge was building beneath the existing structure without compromising its stability. Foundations around the Giacometti and Miró courtyards were reinforced with shotcrete walls, nailed walls, and micropiles. A prestressed honeycomb concrete slab system (14 m long, 36 cm high, 120 cm wide) created a column-free large room beneath the Giacometti courtyard, maximizing ceiling height and material efficiency. Ultra-thin aluminum bay windows enlarge glazed surfaces, ensuring visual continuity with the surrounding pine forest while integrating a sliding module for large artworks. By combining careful structural engineering, minimalist detailing, and sensitivity to context, the project increased exhibition space by 65% while preserving the building’s soul and enhancing the visitor experience.

The project follows a sustainability and environmental preservation approach. Low-carbon concrete reduced CO₂ emissions, and 80% of site waste was recycled. Local and ecological materials were prioritized, including stones from the earthworks to clad concrete walls. Cast-in-place concrete and C30/37 prestressed hollow-core slabs ensure structural performance and architectural flexibility, adapting to varied geometries and finishes. Materials were chosen to echo original textures: restored terracotta tiles, Tivoli travertine floors, and concrete replicating the local limestone base. Energy renovation included replacing single glazing with double glazing while retaining fine steel frames. Accessibility was improved with two PRM lifts, integrated without altering existing volumes. The project balances durability, aesthetics, sustainability, and user comfort, with low-maintenance, robust materials ensuring long-term performance.
