This document provides an analysis of the urban area of Puchong, Malaysia through the lens of Jane Jacobs' theories in her book "The Death and Life of Great American Cities". It examines Puchong's development and layout, then discusses three key principles from Jacobs' work: the importance of busy sidewalks for street safety, allowing contact between strangers while maintaining privacy, and sidewalks providing a safe space for children to play. The analysis finds Puchong currently lacks interaction between residents and safe public spaces for children. Implementing Jacobs' principles through more businesses and activity on sidewalks could help address these issues.
