T The rapid development in jakarta has caused the betawi people to gradually shift and choose to settle in the suburbs of jakarta, one of which is depok. this area is becoming increasingly socially and culturally inclusive, giving rise to a generation known as the betawi pinggiran. the loss of physical characteristics and the application of tectonics in betawi pinggiran houses has led to a lack of knowledge among the younger generation of betawi descendants about what betawi pinggiran houses are really like. this study aims to identify the physical characteristics and explore the tectonics of betawi pinggiran houses in relation to their construction logic and structural expression, which can be maintained in the context of architectural transformation and adaptation. the method used in this research is a qualitative descriptive approach, involving field observations, semi-structured interviews, surveys, and document analysis, focusing on the object of betawi pinggiran houses in depok. the results of the study show that the physical characteristics of the architecture of betawi pinggiran houses in depok have adaptive spatial, physical, and stylistic systems, with a low-pitched stilt house typology, umpak foundations, kebaya roofs, gedhek wall coverings, krepyak doors, double-layered windows with jejake and krepyak, langkan, gigi balang, and balaksuji or gelodog stairs with no more than three steps. tectonically, betawi pinggiran houses demonstrate traditional woodworking techniques that integrate a sturdy substructure, superstructure, and upper structure, with traditional wooden peg and mortise and tenon joints in the beams, columns, and roof trusses, as well as the use of materials that reflect a harmony between local resources and modern materials. this research produced recommendations for a prototype design model that integrates the architectural principles of betawi pinggiran houses, serving as a practical reference for the design of authentic betawi pinggiran houses.
