This dissertation explores the architectural transformation of the early 20th century, influenced by industrialisation and urbanisation. It focuses on redefining the relationship between the exterior and interior of buildings, studying the works of Adolf Loos, Louis Sullivan and Robert Mallet Stevens. Loos advocated for simplicity over ornamentation, Sullivan blended aesthetics with functionality, and Mallet Stevens combined modernism with tradition.
The study highlights their common rejection of unnecessary ornamentation and their quest for functionality, reflecting an evolution of architectural paradigms. It incorporates historical, social and cultural perspectives to show how architecture reflects societal and technological changes, highlighting the impact of these architects.
