This document summarizes a student's reaction paper on the architectural theory of Critical Regionalism. Critical Regionalism aims to provide architecture rooted in the modern tradition but tied to local geography and culture. It discusses how to revive old civilizations while participating in universal civilization. Specifically, it emphasizes the importance of preserving landscapes and local culture to create buildings that resonate with the natural environment and foster a sense of place. The student analyzes an example of a Malaysian house that integrated traditional Malay elements with modern materials. In their opinion, Critical Regionalism should be a flexible approach, and architects should reinterpret local characteristics in contemporary terms rather than directly adapting traditions.
