Exploring user-led spatial practice and user design tools in urban low and middle-income residences: a study based in Kitulwatte, Colombo

In many developing Asian countries, informal user-led architectural production is prevalent, with dwellings designed and built largely without professional input. Unlike traditional architectural practices, where design, construction, and inhabitation are distinct phases, users perceive these aspects as interconnected, influencing each other continuously and simultaneously, resulting in unexpected and rich spatial experiences. This study focuses on informal user-led architectural production in Sri Lanka, examining the design methods users employ through Jonathan Hill’s framework of user creativity types. By analysing the architectural features of user-designed homes, identifying manifestations of user creativity, and assessing the influence of user-led production on urban adaptability and vibrancy, this research aims to underscore the creative and significant architectural contributions of users. Through an analysis of four residences in Kitulwatte, Colombo, the research reveals the conscious and subconscious processes inherent in user-led design, highlighting their substantial contribution to the urban fabric. This holistic approach transforms architecture from a static product into a dynamic process that continually evolves to meet individual needs. By elucidating the unique design tools and approaches employed by users, this paper enriches the discourse on architectural agency and challenges conventional notions of authorship, showcasing the profound impact of user influence on shaping the built environment.
