Gapyeong Sangmyeon Administrative Welfare Center is located in Sangmyeon  in the west, and has a population of about 60 million in 14 administrative districts. However, the following problems occurred due to the lack of budget at the time of this project and the continuous and consistent public design was not applied. As a result of the analysis, the guide sign for civil petitioners to find the Administrative Welfare Center was incorrectly written or absent, causing confusion. In addition, looking at the satellite map of the Administrative Welfare Center, it was urgent to derive basic guidelines such as the movement of vehicles and pedestrians and the complex system of designated parking spaces, which resulted in frequent accidents and the overall design and color of the building. Therefore, through a long-term project, the typeface, pattern, color, shape of sign, size, location, movement of vehicles and pedestrians, color of the building, and interior maintenance of the internal conference room were implemented in a complex manner.
