Changsil Old House is a courtyard hanok in Cheongsong-gun, Gyeongsangbuk-do. It was built in 1917 by Sim Ho-taek of Songso as a home for his younger brother. The anchae (women’s house) and the sarangchae (men’s house) are arranged side by side, with the connected library and storeroom between them. Just inside the gate is a haengnangchae (servants’ quarters), and there is also a thatched hanok which is currently being rented out as a red clay room.
