Architecture Asia, as the official journal of the Architects Regional Council Asia, aims to provide a forum not only for presenting Asian phenomena and their characteristics to the world but also for understanding diversity and multiculturalism within Asia from a global perspective. In the 21st century, Asia has been developed fast in the wave of globalization, and the living and urban environment are changing rapidly along with the economic development. In this process, many Asian cities are carrying out large-scale urban infrastructure construction in the process of rapid urbanization, and building a large number of iconic buildings that represent the characteristics of the country or city. This issue focuses on Living in the 21st Century, through three perspectives: the transformation of spatial functions, the contradiction between urban development and individual dwelling, and architecture in the age of self-media.
