With the global demographic shift towards an ageing population, focusing on architectural designs and space planning in retirement communities is necessary. This research explores the significance of architectural designs and space planning in retirement communities, specifically focusing on the elderly population in Bangalore, India. This study aims to achieve two objectives: providing a basis for developing spaces that promote active ageing and ensuring the peculiar requirements of senior citizens are always considered. The aim of this study is first to elicit from primary sources the dependability of the quantity of safety, comfort, accessibility, and social engagement used to actively promote ageing in contemporary times. The second aim is to analyse and assess the reference experiences of the elderly to determine the extent of architectural planning on retirement communities and the active ageing process of older individuals. Descriptive statistics, correlation and regression analysis, and SPSS software reliability testing were performed. Subsequently, the paper accounts for the proposed guidelines on which the architecture that builds old-age accommodation will be based and the key components of the housing structures that will be designed and constructed. The discussion sets a goal for the existing trends and atypical designs in several retirement communities. Recommendations are offered, ensuring that accessibility is considered, communal spaces are planned, natural light is accounted for, and safety features are considered in the design to promote active ageing in retirement communities.
