Understanding Temporal Trends in Local Government Integrated Office Buildings : Focused on Urban Location and the Functions of Integrated Facilities

Purpose: This study examines trends in location and facility types of 34 newly constructed integrated public office buildings in local governments over the past 20 years, aiming to explore the development direction of integrated public offices. By analyzing location and facility characteristics, the study proposes planning strategies to support efficient usage. Method: The research focuses on location suitability and facility integration efficiency. Locations were classified into central and peripheral areas based on address changes, followed by analyses of relocation distances and transportation infrastructure. The data were divided into four periods of 5 years each to identify trends in integrated public office development. Result: The study finds that early integrated public offices primarily included healthcare, cultural, and welfare facilities, while recent trends show increased integration with sports, residential, and commercial facilities. Over time, the number of offices relocating to peripheral areas has decreased, with more now in central locations. This reflects growing demands for convenience and accessibility for residents, aligning with urban regeneration and regional economic revitalization.
