Abstract

Providing spatial security through visual access in the home is one of the most important components of living in historical textures. This component is directly correlated with the concept of quality and can be influenced by social, economic, psychological, and physical factors. Despite its importance, analysis of the role of visual access in security inside the house from the perspective of spatial structure, configuration, and spatial location is among the top research that has received less attention. The present study deals with the investigation of the visual access indicator of the residential buildings in the historical texture of Bushehr based on the field study and using the space syntax technique in the UCL Depthmap 10 Software. An explanation of how visual access is created in the historical houses of Bushehr and its effectiveness in the improvement of security is the most important objective of the present study. It is qualitative research that is based on an analytical-survey approach in the psychological field. To that end, first, the visual access indicator and its connection with security have been investigated and in the field study section, the indicators have been examined in eleven historical houses. The findings indicate that the visual access indicator in the interior spaces behaves differently when associated with components such as metric depth, integration, and justified graphs. Based on the analysis of the justified graphs, the historical houses of Bushehr are not much complex regarding the access hierarchy and their justified graphs are chained, and access to the interior spaces of these houses is very easy. The results indicate that the highest visual access can be seen in low-depth spaces and with the clustering of the justified graph, the space depth is increased while the visual access is reduced. Also, with the increase in visual access, the security in other spaces is increased and their accessibility is reduced. As a result, in line with the type of space use, the role of visual access is also changed and the increase in this component in the semi-private spaces would guarantee the security of the private spaces.
