<i>Rumoh Aceh</i>: the architectural values of sustainability and tradition of disaster preparedness for Acehnese, Indonesia

Purpose This study explores the existence of Rumoh Aceh (Aceh house), a vernacular heritage house of Aceh, in relation to architectural sustainability and disaster preparedness. The house reflects local wisdom and cultural traditions that embody both environmental harmony and resilience. Design/methodology/approach A qualitative descriptive-exploratory method was used, involving field observations, semi-structured interviews and document analysis. Data were collected from traditional villages, heritage sites and local community members. A phenomenological thematic analysis was applied to interpret and categorize data related to architectural form, cultural meaning and adaptive strategies. Findings Rumoh Aceh features distinct architectural elements such as a stilted wooden structure, Qibla-oriented rectangular layout and steeply pitched roofs. These features function as both cultural expressions and disaster mitigation strategies against floods, earthquakes and wild animals. Symbolic elements – like odd-numbered stairs and elevated platforms – demonstrate a fusion of spiritual values and practical design. The house serves as a model of sustainable living rooted in indigenous knowledge, yet its existence is increasingly threatened by modernization and declining intergenerational transmission. Research limitations/implications The findings emphasize the importance of preserving Rumoh Aceh as a vernacular architectural model that integrates sustainability and disaster preparedness. It also offers insight for integrating traditional values into future spatial planning and community-based resilience efforts. And can serve as an adaptive housing model for modern needs. Practical implications These results are essential input in the context of Aceh houses as buildings with sustainable architecture and disaster preparedness. Originality/value This paper contributes to architectural heritage discourse by positioning Rumoh Aceh as a living tradition with ecological, cultural and disaster-responsive values, highlighting its relevance in contemporary resilience and heritage conservation initiatives.
