Postwar architecture refers to the architectural styles and movements that emerged after World War II, primarily from the late 1940s to the 1970s. This period saw a shift towards modernism, characterized by simplicity, functionality, and the use of new materials like concrete and steel. Architects aimed to address the housing shortages and urban rebuilding needs of the time, leading to the development of mass-produced homes and public buildings. Key movements within postwar architecture include Brutalism, known for its raw concrete structures, and International Style, which emphasized minimalism and open spaces. Prominent architects like Le Corbusier and Louis Kahn played significant roles in shaping this era, influencing urban planning and design principles that continue to resonate today.
