The carpenter, who is a craftsman dealing with wood, is divided into a ranch that builds palaces, temples, or houses, as well as a small ranch that makes furniture, such as a wardrobe, door-gaps, tables, and soban, and other wooden crafts. Building wood refers to the manufacture of small facilities attached to buildings, such as windows, handrails, and closures.

Currently designated as an intangible cultural asset in Gyeonggi Province, Kim Soon-ki is a small ranch specializing in traditional windows and doors. He uses red pine or yuksong when he can't find the spruce fruit, Chumok or Choonhyangmok. The windows he produced include the Wanja Changshi, the Three-Year-Old Gate, the Rainbow Gate, and the Flower Salmun.

To make a flower pattern complete with the best floral print among the windows, several pieces must be cut and combined. Instead of simply cutting and attaching them according to the shape, they make and combine the doorknob in a way that crosses the bite.

He participated in the restoration of Confucian schools, such as Gyeongbokgung Palace, Suwonhyanggyo Local Confucian School, and Hongcheonhyanggyo Local Confucian School, as well as temples and shrines, and produced windows and doors of Seojangdae and Hwahongmun in the Hwaseong Restoration Project.
