Horizontal and Vertical Cities

 



This article discusses the concept of vertical cities, where buildings grow taller due to limited horizontal expansion in urban areas. While skyscrapers are a common response to the demand for more space in core districts of global cities, the author argues that the idea of a self-contained "vertical city" challenges the traditional definition of a city.

The author highlights that the fundamental nature of cities is horizontal, with networks of streets connecting various parts of a settlement. In contrast, vertical cities rely on elevators and separate entrances, promoting separation rather than connection. This makes them attractive to foreign investors but less conducive to community-building.

Another drawback of vertical cities is their physical inflexibility. Aging skyscrapers can be expensive to maintain and difficult to upgrade due to their construction in eras of cheap energy and limited adaptability. Demolishing them is also challenging.

In contrast, horizontal cities, made up of discrete structures, are more adaptable and resilient. Each building represents a smaller bet on the future, and failures can be learned from, allowing for fresh starts and adaptation.

While horizontal cities endure through adaptation, vertical cities may face significant challenges in the long run.
