Technological innovation provides many business opportunities (technopreneurs) that involve various fields of study. Architecture is not an exception; technological advances can create a “hi-tech” masterpiece. There are two fields of study related to the application of architectural technology. First, the use of technology to improve the quality of architectural products, so that the design results are considered to be able to keep up with the times, such as materials and technological elements. Second, a form of architectural preservation that can be used as a guide in following technological developments, such as spatial planning. During the Diponegoro War some of his followers were forced to leave Mataram, then those who stopped in Pekalongan began to introduce batik in three areas: Wonopinggo, Pekajangan, and Buaran in 1825-1830. Gradually, batik production increased, until it is expanded into weaving craft. Both types of clothing production can’t be separated from technological advances, handmade batik is replaced with stamped batik, and the weaving of ATBM production changes to using ATMs. The historical journey that transformed Pekalongan as a well-known clothing city in Indonesia is interesting to study, especially in the architectural field, namely spatial planning formed from local culture. This study discusses the spatial preservation of clothing production houses in three areas in Pekalongan, namely: Pekajangan, Kauman, and Pesindon. The objective of the study was to identify the form of spatial preservation used during the development of clothing-making technology. Descriptive-exploratory research method is used to explore elements of local wisdom used as guidelines for spatial planning. The results of the study elaborate that the layout of the clothing production house in Pekajangan, Kauman, and Pesindon consists of: living room, family room, drying room, and factory. However, there are differences in the location of the drying room. This difference is due to the change in function from residential building to production building, and also from the development of clothing technology. This requires some additional spaces. Based on the research results from the three areas, the factory is a long-lasting and sustainable space category.
