The purpose of this study is to investigate the actual condition of the external space at the boundary of the land of public buildings around the provincial government office in Gyeongsangnam-do. As can be seen in the case of the Gyeongnam Research Institute and the Gyeongsangnam-do Women's Competency Development Center, it was confirmed that the use of space and utilization rate increased for both off-site pedestrians and building users when some walls were opened. If mini trails, resting pagodas, and benches were properly placed adjacent to the site boundary, the awareness and walking accessibility of major entrances and intersections were very good, but there were many places like Changwon Office of Education and Gaya Cultural Research Institute that reduced space efficiency. The space between the sites was spaced 2 to 2.5m apart from each side of the site, with an average margin of 4 to 5m. However, more than half of the surveyed public buildings left outdoor units and piles in the space, and it was confirmed that if they were collectively maintained, the green area rate of the boundary could be increased and used as a walking passage or rest area. If the space between public buildings is planned to be combined from the beginning of development, as the size of the block increases, it is possible to create a pedestrian path through the site and to prevent the pedestrian path from being lengthened by bypassing the block. In particular, if a deck is built in the space between the sites to overcome the difference between the sites, it has been confirmed that a 4-5m wide walkway can be built that penetrates the block in about 10 of the 45 sites to be surveyed. In addition, it was investigated that reconstructing the boundary of the road behind the concentrated public buildings could specialize in the characteristics of the space for each street. To this end, sculptures, landscaping, fence removal, and step overcoming that interfere with walking on the nodular site must be preceded. Repeatedly providing environmental sculptures, spaces for pedestrians to rest, and open spaces in the secured space improves the street environment and creates a sense of direction, enabling specialized walking green areas.
