In architecture, a roof serves purposes beyond shielding humans from their environment. The roof carries with it a range of psychological implications. It serves not only to provide a sense of mental security and protection from harm but also to embody the values and sacred beliefs of diverse cultures throughout history. The diverse interpretations and embodiments of meaning are exemplified through the various sizes and forms of roofs. The roof holds great significance in the symbolic representation of a structure. Throughout history, the roof has undergone its own evolution, and as time passes, people’s perception and memory of this crucial architectural element continue to evolve, shaping the way we view and appreciate it. No longer just a mere protective covering, the roof has now emerged as a dynamic space that is increasingly becoming accessible to the public. It has been designed as a public space that seamlessly connects buildings to the various surroundings of towns and cities. There are times when an interplay between the roof plane and floor surface can evoke a sense of ambiguity, resulting in new experiences for both inhabitants and the surrounding urban environment.

The ASA Journal, themed “On the Roof,” features remarkable works by Thai architects that showcase their unique interpretations and presentations of roofs, as well as a diverse range of construction techniques and materials that are tailored to suit the unique nature and physical characteristics of each building. This issue showcases a diverse range of projects that span across various scales, ranging from public structures to residential buildings.
