Modernist Experiments: Reinventing the Coast

The 20th century brought radical experiments in coastal architecture, as modernist architects saw the clean slate of undeveloped coastline as laboratories for new ways of living. Le Corbusier's Unité d'Habitation in Marseille, while not directly coastal, established principles applied in numerous seaside projects: communal amenities, pilotis to preserve ground plane, and béton brut aesthetics that referenced ships and industrial structures.

La Grande-Motte exemplifies modernist coastal planning at urban scale. Jean Balladur's pyramidal buildings, inspired by pre-Columbian architecture, created a resort city from scratch in the 1960s. Initial reactions ranged from horror to fascination, but time has vindicated the design's intelligence. The pyramids ensure every apartment receives sun while creating wind-breaking courtyards. Pedestrian priority and abundant green space now seem prescient. The architecture, once shockingly modern, has aged into classic status, protected as 20th-century heritage.

Royan's postwar reconstruction represents another modernist approach. Destroyed by Allied bombing, the city rebuilt with aggressively modern architecture, including Guillaume Gillet's extraordinary concrete church with its sail-like roof. The new city rejected nostalgic reconstruction in favor of forward-looking design, creating a coherent modernist ensemble unique in France. Not all experiments succeeded—some concrete buildings suffered in the salt air—but the ambition to create architecture worthy of the atomic age remains impressive.

Individual modernist houses dot the coast, often commissioned by progressive clients seeking to merge indoor and outdoor living. Pierre Chareau's Maison de Verre principles influenced countless coastal houses with glass walls and open plans. Eileen Gray's E-1027 at Roquebrune-Cap-Martin pioneered furniture and architecture designed as total work of art. These houses, many now restored as museums, demonstrate how modernist principles of light, space, and function found perfect expression in coastal settings.
