Abstract In Korea, the prevalence of large, high-rise concrete apartments built since the 1980s exceeds 80 percent. With approximately 60 percent of the Korean population currently residing in such high-rise structures, it is evident that this typology significantly shapes the lives of Koreans. When these buildings reach the end of their operational life, two options typically arise: complete demolition and new construction, or renovation. To extend the lifespan of high-rise apartment buildings while minimizing environmental impact, prioritizing renovation becomes crucial. Moreover, to address the recent housing shortage in urban areas, it is essential to explore methods that increase downtown density by vertically expanding existing concrete apartment buildings. This research endeavors to investigate the utilization of mass timber as an alternative material for the primary structure of vertical expansion. By examining current design methodologies and typological standards, the study aims to establish comprehensive design guidelines for the construction, management, and overall implementation of mass timber vertical expansions on existing concrete apartment buildings. With the guidelines in place, a sample apartment complex will be designed, and extensive tests and simulations will be conducted to evaluate the building’s performance. Of particular importance is the analysis of the carbon footprint associated with this new typology and its ongoing management, taking into account the surrounding environmental system. Furthermore, an assessment of the ecological relationship with the nearby forest system will be conducted, utilizing actual statistics and available technologies.
