Geometric Analysis and Reinterpretation of the Traditional Latch Mirror in the Third Dimensions: The Case of Safranbolu

This study examines the door latch mirrors on traditional Safranbolu residential doors, which carry both formal and symbolic meanings, aiming to highlight their uniqueness and promote their sustainability. It seeks to present viable design alternatives using the shape grammar approach, which is effectively employed to evaluate the design languages of traditional architectural elements through both two-dimensional and, more rarely, three-dimensional analyses. While latch mirrors display rich variations in the patterns on their surfaces, this study focuses on the features of their external forms. Based on these ideas, the first phase of the study involved photographic documentation of existing latch mirrors in the buildings. Common and distinct two-dimensional geometric properties, relationship types, and rules were identified. Using Grasshopper (a visual programming plugin for Rhinoceros), a parametric model was developed based on these defined geometric rules. The study demonstrates its methods and production potential through examples. As a result, new 3D models were generated according to the design rules defined for door latch mirrors. Finally, the findings suggest that the model has the potential to actively support the preservation of traditional craftsmanship by providing alternative methods for restoration and facilitating cultural transmission related to tourism.
