Vernacular houses reflect the social complexity of the times and region in which they exist. These houses are continually evolving in response to changes in the residents’ sense of well-being. However, the rapid progression of modernity and urbanization over the past fifty years has strongly altered the underlying cultural meanings of domestic well-being in traditional societies. This has caused the disappearance of vernacular houses in various localities. The present research is especially concerned with surviving Thai vernacular houses. Its aim is to establish an understanding of the relationship between changes of Thai residents’ experiences of well-being, or Khwam Phasook in the Thai language, and the physical and socio-cultural evolution of their vernacular houses. The study was conducted by examining the evolution of vernacular houses in Tambon Pakkran of Pra Nakhon Si Ayutthaya in central Thailand. Two main types of data were collected: evolution of the physical characteristics of vernacular houses, and the changes of patterns of use and the meanings attributed to them. The data obtained were analyzed and discussed through systemic taxonomy, cross-case analysis and graphical representation using multiple criteria. The residents’ narrations were also used to explicate the historical development of the houses investigated.
