The concept of style is relevant for both analysis and synthesis of designs. New styles are often formed by the adaptation of previous ones based on changes in design criteria and . context. Thus, design styles undergo change over time. A formal characterization of style is given by shape grammars, which describe the compositional rules underlying a set of designs. Grammar rules describe form elements and their organization through shapes and spatial relations. Stylistic change can be modelled by grammar transformations, which allow the transformation of the structure and vocabulary of 11 grammar that is used to describe a particular style. In order for grammars to be useful beyond a single application, they should have the capability to be transformed according to changing design needs. The problem of goal driven grammar transformations based on changes in style goals has not been addressed previously. lssucs of formalizing stylistic change necessitate a lucid and formal definition of style in the design language generated by a grammar. A significant aspect of the definition of style, which !k1S not been addressed in studies of grammars, is the representation of aesthetic qualities attributed to the style. This work investigates the aforementioned issues with the development ofa style description scheme by describing the aesthetic qualities of primitives and spatial relations in a grammar. The description scheme is based on the semantic differential method which has been used earlier to characterize styles in product design. The utility of the style description scheme is tested through examples of Greek temple facade design and mobile phone design. The main contributions of this thesis are: • It presents a technique for the formal definition of style(s) in the design language generated by a grammar.
