Centralization, zoning, and geometry (grid planning) are key urban planning theories proposed by Le Corbusier. In Subang Jaya, Malaysia (SS15), these theories are applied. Subang Square is located in the center of SS15 acting as the main building and economic hub. SS15 is well-zoned into residential, business, education, and religious areas with a clear grid structure. While generally fitting Le Corbusier's theories, the author notes room for improvement in landscaping and maintaining grid order. Proper zone connections and prioritizing greenery could enhance SS15's urban design according to Le Corbusier's principles.
