street-side postmodern landscape design

Quick answer：

Postmodern landscape design refers to a style of landscape architecture that emerged in the late 20th century, characterized by its eclectic use of historical and modern elements, and a break from the modernist principles of simplicity and functionality. It often incorporates varied textures, shapes, and materials, and embraces a more subjective and symbolic approach to design. This style is often seen in urban settings where the design reflects the diverse cultural and historical context of the city.
