An examination of ironworking examples in traditional Safranbolu house doors through the approach of shape grammar

Safranbolu is renowned for its traditional architecture and the local tradition of ironworking in Turkey. The importance attached to sustaining ironworking as well as traditional architectural heritage has led to the launch of a research initiative to study examples of ironworking and to encourage diversification of production. This study uses a mathematical analysis to investigate the latch mirrors on traditional Safranbolu house doors. The research methodology consists of several basic steps. These are the literature data that form the background of the research, their interpretation, and the steps used to implement the proposal. After collecting literature and visual data, the research continued with the two-dimensional digital drawings to reveal the form and components of the door latch mirrors. Then, the analysis of the shape of the keyframe in the plate, the most common ornamental area in latch mirrors, was carried out. Finally, new patterns were produced through the algorithmic process using Rhinoceros-Grasshopper plug-in. This study provides valuable information about the ornamentation techniques used in the traditional house doors of Safranbolu and significantly contributes to the maintenance of local craftsmanship. Importantly, it empowers craftsmen by offering practical benefits by providing sample models and suggestions for improving decorative ornamentation.
