Conventional conservation frameworks often prioritize material integrity and architectural form, frequently overlooking the morphology of the use of interior spaces as a basis of significance. This research explores how the modification and repurposing of interiors, in response to changing community needs, reveal a layer of intangible heritage often missed and overlooked in conventional assessments. Using a qualitative case study grounded in phenomenological principles, the research investigates the Don Luis Palad Gabaldon School in Tayabas City, Philippines. The findings uncover various interior morphologies, spanning from its original use as classrooms, wartime garrison, library, school paper office, guidance office and theatre to a contemporary COVID-19 command centre. How these spaces were used and subdivided highlights the spatial memory from a social and community perspective, wherein the building serves as a mnemonic device for lived experiences. Recognizing the morphology of use as a factor in understanding the significance of heritage buildings, this study suggests the inclusion of understanding the dynamic changes in the use of interior spaces to integrate both tangible and intangible elements, to ensure that heritage structures remain functional, relevant and deeply resonant with the communities they serve.
