The purpose of this study is to estimate the location and space configuration of Sauidang(四宜堂), which is a house in the late Joseon period. Sauidang was built by Hong Man-hoe(洪萬恢), the last son of Princess Jeongmyeong(貞明公主), was used as a house for Pungsan Hong clan(豊山洪氏) for approximately 150 years, and is now defunct. However, the existence was estimated through Sauidang-ji ( 四宜堂志) compiled by Gwan-am Hong Gyeong-mo(冠巖洪敬謨) in 1824. Based on the mention that “Sauidang was located in Hundo-bang(薰陶坊) of Ihyeon-dong(梨峴洞)” and the literature referring to “the site of Myeongryegung Palace(明禮宮)”, this study estimated the location of Sauidang. Maps and photographic data in the modern age enabled us to examine the utilization cases of medium- and large-sized lots by examining the correlation with the current Embassy of the People’s Republic of China in the Republic of Korea. In addition, it was possible to estimate the spatial configuration of Sauidang with a focus on words to clarify the detailed explanation of Sauidang mentioned in the literature and spatial relationship.
