The Old House of Tan Ky is a meticulously preserved merchant residence in Hoi An that serves as a prime example of 18th-century Sino-Vietnamese domestic architecture. Built seven generations ago by a Vietnamese family, the structure combines elements of Chinese, Japanese, and Vietnamese design. The house is constructed primarily from ironwood and utilizes traditional mortise and tenon joinery instead of nails. Its unique orientation allows it to span from Nguyen Thai Hoc Street to the Bach Dang riverside. The interior features intricate wood carvings, mother-of-pearl inlays, and an open-air central atrium for light and ventilation. The house has withstood numerous major floods throughout its history, with water-level markers displayed on internal pillars. It remains privately owned and inhabited by descendants of the original merchant family.
