In several traditional villages, there are still traditional houses that are used by the community as residences. In the past, there were no room dividers in traditional houses; now, residents apply the privacy of each room so that room dividers are added to traditional houses, and there are additional rooms as the need for activities also increases. These changes in activities and use of space have also caused changes in the anthropometry of traditional houses, which are being reused as residences today. So, this research aims to determine whether the spatial pattern transformation in the Sitolumbea Traditional House meets the space standards for simple residences in Indonesia. This research was carried out by directly observing 1 Original Traditional House and 2 Sitolumbea Traditional Houses, which have been transformed to determine changes in anthropometry and the size of the space used. Then, it is compared with the standard size of residential space in Indonesia. Based on the results of the research conducted, the dimensions of the bedroom, bathroom, and laundry room do not meet the standard size of residential houses in Indonesia. Meanwhile, the living room and kitchen require wider dimensions.
