Functional Floor Plan Adaptation for Age-Friendly Housing in the Context of Ageing in Place

Global ageing has further increased and, in line with national conditions, China will adopt ageing in place as the main form of retirement. The number of age-friendly residential space renovations is increasing. At the same time, China’s existing residential stock is large and voluminous, mostly with wall bearing structures. At the same time, due to the current economic situation, the layout of existing homes cannot be modified too much, and the vast majority of homes have to retain their original wall and window and door openings. This requires the designer to have a clearer understanding of the floor plan characteristics of the home, in order to provide the most efficient and age-appropriate space layout for the elderly. In this paper, a common house plan is chosen. Based on the theory of spatial syntax, it analyses in depth the degree of connectivity, integration, control and depth value indicators of the individual spaces of the house plan. The characteristics of each functional space are quantified and analysed, and finally the most suitable space is selected for matching with the specific function. It is hoped that this will provide a cognitive approach to the ageing retrofitting of existing homes in China.
