This study offers two main contributions. Firstly, it introduces the concept and framework of "Section Grammars," (SecG) which is derived from Stiny's shape grammars. Secondly, it investigates the potential of SecG in generating existing and alternative section layouts for ancient underground cities. Derinkuyu, which is located in Cappadocia Türkiye, is thoroughly examined as a case study. The components of Derinkuyu underground city, its parameters, and the rule set depending on the relations between components are presented. Using these elements and rules, an existing satellite city and a new synthetic satellite city are generated. Last, the outcomes of the implementation of the SecG framework are discussed. As an original contribution to shape grammar studies, this research integrates the subtractive (carving) approach and topological relations of the elements observed in the underground cities into the developed framework.
