The second paper examines Semiology and Architecture by Charles Jencks and the concept of multivalent meaning. The third paper analyzes The Geometry of Feeling by Juhani Pallasmaa and how architecture should be experienced through emotions and memory rather than just form. The fourth paper reviews Towards a Critical Regionalism by Kenneth Frampton and the importance of understanding regional context and culture in architecture.
