THE USE OF MATERIALS AS A MEANS OF COMMUNICATION IN 20TH CENTURY ARCHITECTURE: A CASE STUDY OF FRANK LLOYD WRIGHT, MIES VAN DER ROHE, AND LOUIS I. KAHN

Abstract

Background and Objectives: This study examines the paradigm shifts in twentieth-century architecture shaped by rationalist and functionalist thought. While modernist discourse has long emphasized the concept of “material honesty,” it has rarely treated materials as a language that conveys the architect’s design intentions. The research therefore investigates how Frank Lloyd Wright, Ludwig Mies van der Rohe, and Louis I. Kahn use materials to communicate meaning, and why material-based communication is significant in architecture.

Methods: A qualitative comparative analysis was conducted on photographs, drawings, and archival texts of six canonical buildings by the three architects named above. Each case was interpreted through a material-as-language framework considering the type of materials, its mode of display, and the message it transmits.

Key Findings: Materials in modern architecture function far beyond structural or aesthetic elements, they act as rhetorical tools that express relationships between human and nature, industrial progress, and the intrinsic character of materials themselves. These material strategies stimulated innovation in both material development and construction technology that continue to influence contemporary practice.

Implications of the Study: The analytical framework clarifies how technology, context, economics, and aesthetic philosophy intersect in the selection and use of materials. Interpreting materials as a language opens new dimensions for contemporary architectural design to communicates cultural values and sustainability with greater clarity.

Conclusions and Future Study: Architectural materials play a significant role as a language convey of expressing deeper meanings within architectural discourse. Future research should explore contemporary, sustainable, and alternative materials, including user perception, to further understand how material communication functions within present-day architectural contexts.
