The foreigners' company housing in Ul-san is a research subject that has important implications for the technology transfer process of the Korean petroleum industry. Examining the foreigners' company housing in the 1960s and 1970s is also to more closely understand the architectural response methods of companies that made efforts to lay the foundation for production in the early industrialization stage of Ul-san. This study examines the spatial composition of the housing that was planned to contain the lives of foreigners, which was different from the Korean style of residence, and attempts to clarify the construction method that was selected for this purpose. Through this, compared to the domestic housing, the architectural characteristics of the foreigners' housing in the early stages of the creation of the Ul-san industrial complex are to be more clearly understood.
