Plan Voisin, Urban redevelopment project in central Paris, France.
Plan Voisin was a radical redesign scheme for Paris's Right Bank featuring eighteen identical skyscrapers arranged in a grid pattern across roughly 260 hectares. The design set aside eighty-eight percent of the land for parks and roads, with buildings occupying only twelve percent of the total area.
French-Swiss architect Le Corbusier designed this radical scheme in 1925 as a response to housing shortages in Paris. The concept embodied his vision of a modern city grounded in scientific planning and functional order.
The plan intended to replace traditional Parisian streetscapes with modernist towers, sparking fierce debate about preservation and urban change. These discussions reveal how deeply questions about progress and continuity shaped thinking on city development.
The plan exists today only as a historical concept and was never built in Paris, so visitors can only view historical documents and exhibits. Museums and architecture centers in the city display plans and models to understand the radical thinking of that era.
The project proposed a population density far exceeding typical Parisian standards of the time, with roughly 1.200 people per hectare planned for the site. This extreme concentration represented a vision much bolder than anything existing in European cities then.
