The study of vernacular architecture in Indonesia has predominantly focused on documenting architectural features, capturing the static morphology of spaces at specific times. However, the dynamic and ongoing process of spatial production in vernacular architecture has received minimal attention. This research investigates the production and reproduction processes of vernacular architecture in Java through a qualitative inquiry.This research employs Henri Lefebvre's theory of the production of space as a reference to analyze how space is produced and reproduced, particularly in the context of vernacular architecture in Java. The methodology involves a visual observation, comparative visual analysis, and direct experience. Secondary data was collected through a literature study utilizing a Systematic Literature Survey. The theory of the production of space developed by Henri Lefebvre is used to analyze the evolution and transformation of vernacular architecture in Java over time.It concludes that spatial practices, representations of spaces, and representational spaces, as conceptualized by Lefebvre are factors that influence the production and reproduction of space. However, research findings also reveal other factors: environmental, economic, pragmatic, hybrid and new spaces, and educational factors that influence the production and reproduction process in vernacular architecture of Java.
