Abstract: Public rental housing complexes in South Korea have played a critical role in addressing housing needs since their introduction in 1989, initially prioritizing rapid quantitative supply. However, challenges such as limited housing quality and evolving socio-economic demands have prompted a shift toward emphasizing qualitative improvements in residential environments. This study investigates changes in residential building layouts in public rental housing complexes constructed during the 1990s, 2000s, and 2010s to understand how planning practices have evolved over time. Using a structured analysis framework, this research examined layout types (orthogonal, parallel, staggered, and mixed) and key planning elements (density, building height, orientation, and building forms) across 24 complexes. The findings reveal a transition from orthogonal layouts with uniform linear flat-type buildings in the 1990s to mixed and parallel layouts incorporating tower-type buildings in the 2000s, reflecting an increased emphasis on density and aesthetics. By the 2010s, parallel layouts persisted but featured diverse building forms, such as modified flat-type buildings and L-shaped configurations, along with variations in floor heights, enhancing spatial efficiency and visual appeal. These changes in the layout forms of residential buildings are particularly driven by the combination of planning characteristics, such as building forms and orientation as well as socio-historical factors. Relevant legal frameworks and institutional systems, such as district unit plans, have played a significant role in shaping these transformations. This study provides insights into the evolution of public housing planning and offers guidance for sustainable and high-quality urban housing development.
