King Jeongjo built the new Suwon city and constructed the city fortress. Hwaseong Hawnggung and other official buildings were also built in Suwon Hwaseong. However Those buildings were demolished gradually and lost their identity during Japanese colonial period. The official buildings of Hwaseong Haenggung were classified into nine parts. 1) Central area of Hwaseong Haenggung 2)Nangnamheon(落南軒) 3)Uhwaguan(于華館) 4)Namgunyeong(南軍營) 5)Bukgunyeong(北軍營) 6)Gangmudang(講武堂) 7)Yiah(貳衙) 8)Jungyeong(中營) 9) Hoeryungjun(會寧殿).

After opening Suwon railway station in 1905, a new road was constructed between Suwon station and Paldalmun(the South gate). It was the starting point to change urban structures of Suwon and shape the new city scape. In 1914, administrative districts of Suwon were reorganized. Suwon-myeon (township, a subdivision of Suwon-gun) was promoted to Suwon-eup(town) in 1931. Suwon-eup expanded its territory and changed the address system from ‘li(里)’ system to Japanese address system, ‘Jeong(町)’ in 1936. From 1920s, road system was changed and transformed Suwon’s urban structures. A straight road was built from Jongro intersection to Janganmun(the north gate) in 1928. Another straight road was constructed between Suwon station to Padamun in the early 1930s. Public office buildings used the Hwa Seong HaengGung(華城行宮) and some of building moved to new location with new buildings. Main buildings of most schools in Suwon were reconstructed since 1930s. Commercial buildings and stores were sprung up and had their own characteristics by region. Around Suwon station, there are more hotels and restaurants than other areas. Rearranging administrative areas, developing road system and new buildings transformed Suwon’s spatial structures. Constructing new roads formed a straight road passing through Suwon. After reorganizing administrative areas, this road turned to be the central axis of Suwon. Buildings in new style on the axis made the modern cityscape in Suwon.

The Agricultural Experimental Organizations[勸業模範場] in Suwon is Korea's first agricultural promotion facility. It was founded in 1906. This study aim to find the area and spatial composition of 勸業模範場. The results are as follows. When it founded, the Agricultural Experimental Organizations was operated centering on the main hall, and then since the pillage of national sovereignty in 1910, it was moved to the jurisdiction of the Japanese Government General of Korea and operated with the addition of the agricultural/forestry school. In 1913, the reductive egg production/distribution was moved from Yongsan branch to Suwon, and reductive egg producing site and female sericulture training office were installed in Suwon. It is supposed that at the time, the Agricultural Experimental Organizations was divided into the main hall-centered area, the Suwon agricultural/forestry school at the south side, and the reductive egg producing site and female sericulture training office even more down south. Since 1920, the agricultural/forestry school came out of the jurisdiction of the Agricultural Experimental Organizations, such that the Agricultural Experimental Organizations was left with only the main hall-centered area and the area with the reductive egg producing site and female sericulture training office. In this study, these two areas are referred to as 'the main hall area' and 'the sericulture area'.

The purpose of this study is to clarify the identity of the Suwon Hanok. To prevent indiscriminate distortion of the space and many systems of the Hanok, in this study, before realizing Hanok activation policy, we want to trace the original form of the Suwon Hanok by the investigation and measurement. Ultimately to promote the Suwon Hanok, is expected to raise its base. First, to determine the status of Hanok in the sanctuary, the actual total was 38. And this space is divided and analyzed the space and the systems. As a result, the Suwon Hanok, similar to the plan of a private house Hanok in Seoul, which is ㄱ shape. Through research on Hanok, the only one to control the physical environment, as well as improving the quality of life of Hanok secured and identity can be obtained. Hanok policy before extending the number of objects, the more study of the identity establishment is required.
