Urban Planning Theories and Concepts

Garden Cities

• Sir Ebenezer Howard's model city proposed in 1902 focused on creating self-contained communities with green spaces, parks, and a balanced mix of housing, industry, and agriculture.
• This concept aimed to address the problems of overcrowding and pollution in industrial cities of the time.

Geddesian Trio Concept

• Sir Patrick Geddes, in 1909, proposed a “Trio Concept”, which focused on an integrated approach to urban planning, acknowledging the interconnectedness of the physical, biological, and social aspects of a city.
• His ideas focused on social reform and revitalizing cities through social progress.

Concentric Zone Theory

• Earnest Burgess, in 1925, proposed a model that illustrated city growth as a series of rings radiating outwards from a central business district.
• The theory suggested a clear pattern of land-use, with different social and economic groups occupying specific zones.

Sector Theory

• Homer Hoyt challenged the concentric zone theory in 1932 by introducing a sector model, suggesting that certain types of land use would grow in wedge-shaped sectors out from the city center.
• He argued that high-income residential areas, for example, would expand along radial lines, influenced by factors like transportation routes, topographic features, and access to amenities.

Multiple Nuclei Theory

• In 1945, C.D. Harris and Edward L. Ullman proposed the multiple-nuclei theory, which focused on the idea that cities could develop multiple centers, each with its own distinct functions and activities.
• This theory acknowledged the increasing decentralization of urban functions and the emergence of new areas of economic and social activity.

Neighborhood Unit Theory

• Clarence Perry, in 1929, focused on designing self-contained, walkable neighborhoods with a focus on community building, safety, and accessibility. This is known as the Neighborhood Unit theory.
• He proposed a model with schools, parks, and shops within walking distance for residents, ultimately promoting social interaction and a sense of place.

Linear City

• In 1883, Don Arturo Soria Y Mata envisioned a Linear City, a long, narrow city with a central spine of industry and transportation.
• This concept proposed a self-sufficient urban structure that would spread efficiently along a linear axis, aiming for a balanced growth and less reliance on traditional radial city models.

Radiant City

• 1922, Le Corbusier suggested the Radiant City, a utopian vision for a modern city characterized by high-rise buildings, green spaces, and efficient transportation systems.
• The idea focused on segregating land use, and maximizing density to avoid traffic congestion and promoting a highly centralized urban structure.

Central Place Theory

• Walter Christaller in 1933 proposed a model that explained the distribution of urban centers based on their function and size.
• The theory suggested that larger cities provide a wider range of goods and services and serve a larger hinterland, while smaller towns would offer goods and services for their immediate, smaller area.

Radburn City

• Clarence Stein and Henry Wright's 1929 Radburn City model proposed a residential development centered on a car-free community with pedestrianized streets and green spaces.
• It exemplified the idea of a garden city concept with focus on pedestrian prioritization, creating a safer and more walkable environment.
