Applying the Kano two-dimensional model and quality function deployment to develop sustainable planning strategies for public housing in Taiwan

The worldwide issue of high housing prices has significantly affected the general population's inhabitation right and their willingness to purchase homes. The governments of all countries have been actively promoting public housing policies to help satisfy daily living requirements for all social classes. However, many differences exist in the design requirements for public housing and typical housing design, and the lack of discussion on these differences has caused design outcomes to often fail in meeting users' requirements. This study first adopts the Kano two-dimensional quality analysis method in an attempt to define the real needs of public housing users; subsequently, based on the quality function deployment method, it transforms the design requirements into a design strategy. The research findings indicate that future public housing must focus on multi-generational living arrangements, energy-efficient and barrier-free designs, flexible spaces, crime prevention, self-sufficient farming, and other such areas to satisfy the needs of different users. This study practically bases its case designs on a design strategy and obtained feedback from users to understand the expectations and cognitive differences between designers and residents.
