The uniqueness of traditional houses in Kasepuhan Sinar Resmi lies in the use of natural materials. However, over time, this uniqueness has become increasingly rare. The contributing factors include a lack of public awareness about the importance of preserving traditional house culture, the absence of standardized designs, uncertainty regarding the quantity of required building materials, and difficulties in sourcing materials. If left unaddressed, these issues could lead to the loss of the uniqueness of traditional houses. This study employs observation methods to produce designs that align with ancestral traditions, interviews to gather detailed information, and structural analysis based on SNI 7973:2013 standards using the SAP2000 application. These approaches aim to determine effective and safe wooden material dimensions in accordance with Indonesian standards. The primary goal of this research is to produce a traditional house design that meets both cultural and national standards, serving as a guideline for the Kasepuhan Sinar Resmi community in building traditional houses. Additionally, the findings are expected to serve as a reference for policymakers in providing resources for building materials, supporting the preservation of these unique traditional houses.
