Chusa Kim, Jeong-hui’s old house was originally situated in Jang-dong, Seoul. Once villainous councilors appealed to the king stating the house was too big, it was relocated into its current place Sinam. Chusa’s great grandfather Wolseongui Kim, Han-sin tore down the original house and restored it into 53-kan house. The old house of Chusa Kim, Jeong-hui, a calligrapher as well as a great practical scientist representing the late Joseon, covers 80.5 pyeong and has Anchae (a main building), Sarangchae (a detached building), Munganchae (a building beside the entrance), and Sadangchae.
Including 6-kan Daecheong (a main big-floored hall), 2-kan Anbang (a main room) and Geonnonbang (a room across the main living room), Anchae, the main building for men, is a-type(rectangular type) building with a kitchen, an inner gate, a small side gate, and a storeroom. Since Anbang and Geonnonbang with Toetmaru (a narrow wooden verandah), the kitchen’s ceiling connected to the loft over the kitchen, and Daecheong between Anbang and Geonnonbang are not the usual scale, such a-shaped building is called 「Daegotjip (a wealthy man’s house)」type building distributed mainly in the districts of Jungbu (Central parts of Korea) and Yeongnam (Southeastern parts of Korea). Sarangchae, the detached building for women, consists of a one-kan ondol room (underfloor heating room) to the south, a two-kan ondol room to the east, and the rest of Daecheong and Maru (a small floor). Confucianism affected the concepts of building houses during Joseon Dynasty that made Anchae and Sarangchae strictly divided. A stone pillar with carved letters Seoknyeon(石年) in front of Sarangchae’s terrace stones is a sundial measuring time by shadows made by Chusa himself.
