PurposeThis study is to develop an accurate assessment tool to identify the factors that may influence determining the appropriate use for historic buildings.Design/methodology/approachThe research method in this study is qualitative. The integrated MCDM (multi-criteria decision-making) method is used to determine the most appropriate use for historic buildings, which ultimately led to the development of the MAU (most appropriate use) model.FindingsThe results of this study show that, in terms of preserving identity and cultural heritage, the role intangible criteria have to play is seemingly more important than that of tangible criteria. Also, weighted criteria in the matrix relating the “use” options demonstrate cultural-social, commercial and educational uses being apparently more important than other uses.Originality/valueThe novelty of this research is in providing a framework to facilitate contribution to determine the most suitable use for historic buildings with the ability to set criteria and separate weights for each building aiming to increase the useful life to the maximum extent and delaying the need for a subsequent major overhaul.
