Abstract: The conservation of heritage buildings is a crucial topic in architectural practice because it focuses on
both physical protection and the interpretation of the values they embody. In this context, architects
play a vital role in integrating the principles of the Vitruvian Triad: firmitas (strength), utilitas (utility),
and venustas (beauty). Indonesian conservation policies encompass protection, development, and
utilization, involving multidisciplinary roles including architects, although their implementation still
faces various challenges. This study aims to examine the role of architects in the conservation of
heritage buildings by emphasizing a comprehensive understanding of architectural values. The method
used is a qualitative approach involving direct observation as well as a theoretical review of
conservation and regulations in Indonesia. The research findings reveal that building conservation is
not merely a physical process but must also consider the value systems embedded in the building’s
massing, interior and exterior spatial layout, elements, and ornamentation. Additionally, the integration
of Performance-Based Design (PBD) and Evidence-Based Design (EBD) approaches is necessary to
bridge the demands of contemporary functionality while maintaining the building’s historical
authenticity. In addition, it is necessary to integrate Performance-Based Design (PBD) and EvidenceBased Design (EBD) approaches to reconcile contemporary functional requirements while preserving
the building’s historical authenticity. Architects play a strategic role in interpreting the significant
value of heritage buildings and translating that value into design interventions through the principles
of maintenance, repair, replacement, and addition |
