Urbanism is the study and practice of how cities are designed, organized, and experienced. It examines the relationship between people, buildings, public spaces, infrastructure, and the natural environment, aiming to create functional, sustainable, and socially vibrant urban areas.
Urbanism goes beyond architecture by focusing not only on individual buildings but on the broader systems that shape everyday urban life
transportation , housing, public space, economics, and community interaction. Good urbanism seeks balance between density and livability, accessibility and identity, growth and environmental responsibility.
The foundations of modern urbanism were shaped by several influential architects and planners. Camillo Sitteemphasized the artistic and human-centered qualities of historic cities. Ebenezer Howard introduced the Garden City concept, proposing self-contained communities surrounded by green belts. Le Corbusier promoted modernist planning with rational layouts, high-density housing, and separation of urban functions. Jane Jacobs challenged modernist ideas, advocating mixed uses, walkability, and lively street life based on real social behavior. Ludwig Hilberseimer and Walter Gropius contributed to functionalist planning tied to industrial modernity, while Kevin Lynch later focused on how people perceive and navigate cities. A radical rethinking began with Constant Nieuwenhuys and his project New Babylon, which imagined a flexible megastructure-city for a post-work society.
Constant proposed urban space as continuously transformable, prioritizing play, movement, and collective creativity rather than fixed planning. Urbanism became an open system shaped by its users.
This experimental vision later shifted toward analytical urbanism through Office for Metropolitan Architecture (OMA) and Rem Koolhaas. In works such as Delirious New York,
Koolhaas interpreted the contemporary metropolis as a product of density, capitalism, and contradiction, arguing that chaos and congestion are fundamental drivers of urban form rather than problems to eliminate.
Building on these ideas, XDGA explored post-suburban conditions in After Sprawl. Their research reexamines dispersed urbanization and proposes new territorial structures reconnecting fragmented landscapes. Central to this is the Green Heart, a preserved ecological core within the Dutch Randstad that balances urban expansion with environmental continuity.
XDGA reframes urbanism as landscape-based strategy, integrating ecology, infrastructure, and regional scale planning.
Together, these approaches redefine urbanism as adaptive, critical, and ecological—moving from fixed city models toward flexible, networked territories shaped by social imagination and environmental systems.
Together, these figures established the core principles of urbanism: human experience, spatial organization, social interaction, and the long-term shaping of urban environments.
