Critical regionalism and the art of the façade: a diachronic study of Vietnamese public architecture

The artistic façade of Vietnamese public architecture has been mostly overlooked since the colonial period in both theory and practice. The paper examines its evolution and contemporary revival within culture-based innovation. By looking at world history, the research affirms Vietnam’s façade as a mutable component, continuously reconciling foreign influences with indigenous culture. Using historical, aesthetic, and synthesis methods, the research schematizes Vietnamese architecture’s development process via three main stages: the bioclimatic vernacular, the Indochinese style, and the post-colonial modernist. The analysis points out a significant resurgence, not nostalgic mimicry, in the contemporary era, driven by sustainable cultural spaces and a critical re-engagement with tradition. The results clarify the fundamental façade’s characteristics, such as patterned cultural motifs, formal multi-layered mediation, and material ecological reproduction. The study comes to the conclusion that modern façades function as multi-purposeful skins, where ornamentation is turned into performance, promoting urban identity, harmonizing the surroundings, and communicating cultural narratives. The results contribute to creating a Vietnamese architectural identity that is appropriate for local culture as well as technological and ecological demands of the twenty-first century.
