Re-read of Court's Form and Related Spaces with Shape Grammar Case Study: 100 Houses of Qajar Dynasty in Kashan City

There are several reasons why the maintenance of spatial relationships is important in residential homes. Research in this area is being performed on more than 100 homes from the Qajar era in Kashan City to determine the presence of open, half open, and closed spaces, and based on these relationships shape grammar is being used to create a variety of designs. Shape grammar is a manufacturing system within which a set of rules leads from the desired form to the design.
In this study, three spatial types are considered: a courtyard space (open space), an eyvan (partial closed space), and a closed space. Based on these three spatial elements, design plans consist of three types: single court, double court, and complex. Spatial relationships within the homes are defined using the manufacturer’s specified rules and this algorithm. As it turns out, with the use of these specified rules and allowable spatial types an infinite number of design solutions can be provided. The use of shape grammar to interpret tradition home design in Kashan City lead to the creation of many new designs that are displayed through the use of a decision tree. The goal of this research is to allow for novel home designs while maintaining the essence of traditional Qajar home architectural style.
