Shape Reproducibility and architectural symmetry during the Chalcolithic period in the southern Levant

► We developed a new method, Shape Reproducibility, which compares between architecture shapes. ► CSM results suggest that architectural symmetry does not increase through time. ► Intra-site Ghassulian architecture exhibits low variability in relation to EB Arad. ► Hierarchical social organization cannot be inferred from Ghassulian architecture.
