This is the head house of the Choe Clan in Gyeongju. According to legend, it is located on the site of Yoseokgung Palace of the Silla Period. Descendants of the clan have continued to live in the house over the past nine generations. It is said that it was built around 1700, but this is not certain. The house comprises the anchae (women’s quarters), sarangchae (men's quarters) and daemunchae (servants’ quarters). The daemunchae has a small room and a big repository. The sarangchae, which used to be located in the "inner" yard, no longer exists, as it was destroyed along with the byeoldang (detached quarters) by fire in November 1970. The anchae, which is located at the back of the sarangchae site, is built in the open-style square-shaped form, but originally it was built in the square bracket-shaped layout, forming a harmony with the upside-down-shaped sarangchae and the jungmunchae (living quarters near the middle gate) in the straight layout. A family shrine is located at the northwest of the anchae. At the back of the anchae there is a flower garden, which adds an element of architectural beauty. This house is a typical one of the nobility of the Joseon Dynasty and has been well preserved, so it is considered a valuable resource in the study of traditional Korean architecture. The name of the house used to be “Choe Sik’s House of the Gyeongju Choe Clan” at the time of its designation as an important heritage, but it was changed to “Historic House of the Gyeongju Choe Clan in Gyo-dong, Gyeongju” as the descendants of the clan have been living in it over several generations and it is well known in Gyeongju as “Choe Clan’s House in Gyo-dong.” (Jan, 29, 2007). * The house is usually open everyday, but it might be closed on occasion due to the owner’s personal circumstances.

庆州崔氏大宗宅，相传这里是新罗时代‘瑶石宫’所在之处。祖祖辈辈传了九代，据说大约建于1700年间，但是确切的建造时期不明。建筑物由舍廊、里间、大门间等构成，其中大门间里有小配房和大仓库。舍廊曾位于内院的对面，由于1970年11月发生的火灾，和别堂一并被烧毁，现在只留着旧址。舍廊旧址后面的里间看似呈敞开的“口”字形，但实际上的结构呈‘ㄷ'字形平面，和‘ㄱ'字形舍廊和‘一'字形中门间相配。此外，里间的西北侧有单独建盖的家庙，向南边笔直延伸的道路给人的印象较深刻。里间后面有花园，为宗宅增添了美丽的景致。整座房屋大致上比较完好的保存着朝鲜时代两班（贵族）住宅的原貌，成为了重要的研究资料。指定当时的名称是‘庆州崔植氏家屋’，但由于这里是庆州崔氏家族代代居住的住宅，而且作为庆州有名的富豪‘校洞崔氏豪宅’而名声远播，所以将名称改为了‘庆州校洞崔氏古宅’(2007.1.29)。
