NOW AVAILABLE | The City’s Essential DNA and its Pattern

The City’s Essential DNA and its Pattern covers the most essential aspects of physical form at work in the design of all cities from older, highly-localized urban grids in the Middle East/Africa to deformed grids in Europe to regular grids in the United States/Americas. All cities utilize these (usually geometric) properties, though the scale at which they are realized will tend to vary during urban growth in defining a distinctive spatial culture. The purpose is to provide an understanding of the basic typologies/geometries of urban form that can be found underlying all settlements around the world, to one degree or another (1.0 hour course).

Key concepts: grid expansion, block manipulation, linear extension, grid deformation, discrete separation, and urban blocks.

Instructor: Dr. Mark David Major, AICP, CNU-A
