Few architects have marked their era as much as Charles-Édouard Jeanneret-Gris, better known as Le CorbusierA key figure of the 20th century, he was not only an architect, but also an urban planner, painter, sculptor, and theorist. Born in 1887 in La Chaux-de-Fonds, Switzerland, and naturalized French, he devoted his life to thinking about an art of building in harmony with human needs and the changes of the modern world. His ambition: to rethink cities and housing to adapt them to industrial society and population growth. His ideas, sometimes admired and sometimes criticized, have shaken the foundations of contemporary architecture and continue to inspire today.
The father of modern architecture
Le Corbusier is considered one of the founders of modern architecture. He was the first to question the traditional forms inherited from the 19th century to propose a new aesthetic, centered on simplicity, functionality, and rationality. Inspired by machines and industry, he saw housing as a 'house-machine,' a now-famous expression, where each element had to have a precise and useful function. This vision led him to develop what he called the Five points of modern architecture : the stilts, the roof terrace, the open plan, the ribbon window, and the free facade. These principles, simple but revolutionary, paved the way for airy, light-filled constructions adapted to modern life.
One of his major contributions was also the use of reinforced concrete, a material that allowed facades to be freed and interior spaces to be made modular. Through this architectural language, Le Corbusier imposed a new aesthetic: geometric, simple, yet always conceived in relation to light and space. His ideas quickly crossed the borders of France to influence entire generations of architects, from Europe to Asia.
The housing unit: inventing the vertical city
Among his many contributions, the concept ofHousing unit undoubtedly remains one of the most remarkable. Developed as early as the 1920s, this model aimed to address the housing crisis by offering buildings capable of bringing together, in a single space, all the services necessary for daily life: shops, school, daycare, library, sports facilities, and common areas. A true 'vertical city' where each resident could find comfort, autonomy, and friendliness.
The first major achievement of this model was the Radiant City of Marseille, inaugurated in 1952. Measuring 135 meters long and 56 meters high, it houses nearly 360 duplex apartments, organized around “interior streets.” Its rooftop terrace, converted into a public space with a swimming pool, gym, and daycare, perfectly illustrates the vision of collective housing conceived as a complete living environment. This unit was followed by others in Rezé, Briey, Firminy, and even Berlin, confirming the global influence of this project. While some criticized the coldness of these large complexes, others see in them a pioneering solution that inspired social housing programs in many countries.
Utopian urbanism: the radiant city
Beyond architecture, Le Corbusier profoundly influenced urban thought. In his works, he develops the concept of the Radiant city, an ideal city organized according to four essential functions: living, working, moving around, and cultivating oneself. For him, urban planning had to primarily serve humanity, by providing space, light, air, and modern facilities. His most ambitious projects, such as the Voisin Plan for Paris In 1925, or the plans for Algiers, Barcelona, and Rio de Janeiro, proposed to destroy the unhealthy centers to replace them with vast towers surrounded by green spaces and served by wide traffic roads.
These visions, sometimes considered radical or even dehumanizing, nevertheless shaped the urban imagination of the 20th century. They inspired post-war reconstruction and fed the reflection of many urban planners. The city of Chandigarh in India, designed in the 1950s at the request of Prime Minister Nehru, remains the largest urban planning project he undertook. Entirely conceived by Le Corbusier, this capital of Punjab embodies his ideal: a rational, functional, and harmonious organization of urban life.
Le Corbusier's design
While Le Corbusier is above all recognized for his architecture and urban planning, his influence also extended to design and furniture. In the 1920s, he collaborated with Charlotte Perriand and Pierre Jeanneret to design a series of furniture that would become iconic. Their approach is the same as for architecture: functionality, comfort, and simplicity of lines.
The chairs and armchairs that he designs, like the LC2 and there LC3, stand out for their visible tubular metal structure and their rectangular cushions with precise proportions. The famous LC4 lounge chair, nicknamed 'rest machine,' perfectly embodies its idea of furniture conceived as a rational extension of the human body: adjustable, ergonomic, and elegant.
These creations, produced from 1929, broke away from the decorative forms of the 19th century and were part of industrial modernity. Even today, they are published by Cassina and remain emblematic pieces of modern design, present in museums as well as in contemporary interiors.
Through this furniture, Le Corbusier proved that his ambition went beyond architecture: it was about designing an overall art of living, where each object – from the building to the chair – had to meet the essential needs of modern man.
The heritage and global recognition
If Le Corbusier's work has often sparked passionate debates, his legacy is now recognized worldwide. In 2016, seventeen of his creations, including the Villa Savoye in Poissy, the Convent of La Tourette in Éveux, and the Notre-Dame-du-Haut Chapel in Ronchamp, were listed as UNESCO World Heritage sites. These buildings testify to his ability to combine geometric rigor and architectural poetry, monumentality and intimacy.
His influence extends beyond the strict framework of architecture. His ideas on housing, urban planning, and the art of modern living continue to inform contemporary thinking about the city and housing. In a world where urban densification and environmental challenges raise crucial questions, Le Corbusier's work appears more relevant than ever. His experiments, sometimes utopian, have opened paths that are still explored today by architects and urban planners.
"Architecture is the masterly, correct, and magnificent play of masses brought together in light. Our eyes are made to see forms in light: light and shadow reveal these forms." - Le Corbusier
Le Corbusier was much more than an architect: a visionary, a thinker, and a provocateur who profoundly changed the way we conceive housing and cities. His achievements, bold and innovative, continue to inspire and provoke questions. While some of his utopias never came to fruition, they testify to his audacity and his desire to create a more functional, brighter, more human world. Between admiration and critique, his name remains inseparable from modern architecture.
