The influence of the types of architectural space on the residents' consciousness of shared space, targeting mixed-status-family traditional residential buildings in the West Street area of Quanzhou City, Fujian Province, China was studied. The research was conducted through surveying, mapping, and an investigation of the current state of the buildings' atria by using data statistics and function-fitting analysis. The study included the following four stages: 1. Because of modernization and urbanization, traditional buildings have been transforming from single-family to multi-family, leading to amalgamation. 2. With the emergence of amalgamated buildings, the shared space between households has changed from a street space to an atrium space, which is the most influential and includes three types: porch enclosure, hallway connection, and direct pathway. 3. The shared space consciousness of occupants was simulated by investigating how the overflow (two-and three-dimensional) of the atrium has been used. 4. The influence of space types on the consciousness of shared space is elucidated using data statistics and function-fitting analysis.
