Change in Adaptability of Residential Architecture: Spatial Analysis on Traditional and Contemporary Houses of Bangladesh

This study focused on spatial analysis to identify the changes inadaptability over the last five decades. The features influencing adaptabilitywere selected from the reference study. An appropriate method was used toanalyse these features through spatial analysis. Six distinctive typologiesof rural houses were selected from six regions. Unlike the traditionalhouses, the contemporary houses in the same area reflected a differentcharacter. Urban houses built since the early and mid-20th century werecompared with contemporary houses. After analysing the openness,generality, flexibility, depth, typicality, construction technique, involvementof end-users, and the feedback from the inhabitants, the study identified asignificant decrease in contemporary houses' adaptability. Spatial analysiswas used to quantify the different features and comparison betweentraditional and contemporary houses. Though the adaptability had beenreduced over time, the latest houses started to achieve better flexibility insome features due to government policy and implementation of statutorybuilding regulations. Further recommendations were provided to enhancethe residential architecture's adaptability in future. The study samples wereselected from different regions of Bangladesh. Still, the result and policyrecommendations can be helpful for other countries, especially with highpopulation density and a developing economy.
