Mutation or Reusing: A Decision Based on Functional Analysis of Historical Houses’ Configurations

The present study aims to explore the relationship between theory and practice by evaluating the feasibility of quantification and evaluation for assessing the spatial performance and circulation logic in historic domestic architecture to inform adaptive reuse strategies. The study examines several courtyard houses in a representative residential area within Erbil Citadel in the Kurdistan Region of Iraq, an area of immense cultural, architectural, and historical value. The selection of the sample is based on the chronological, typological, and spatial diversity of residential architecture in Erbil Citadel. The study uses an integrated methodological approach to investigate the spatial configuration of each sample building. To ensure increased analytical rigor and to compare its findings with similar studies in different contexts, the results are further validated using Euclidean distance and Pearson correlation to assess the compatibility of existing characteristics with proposed adaptive reuse strategies across different contexts. The results show that quantitative spatial analysis can be an effective tool in identifying the potential of existing residential architecture in terms of its spatial configuration while preserving its cultural value. The study concludes that its proposed approach can serve as an effective model for adaptive reuse planning in similar contexts.
