We focus on facades of historical buildings with identical purpose located in a specific geographical area. We have chosen the CGA shape grammar as a formal language to represent and visualise the rules and we demonstrate our approach on facades of the residence-type historical buildings located in Prague. Our aim is to show that differences in formal descriptions of various buildings are tightly related to differences in architectural styles. Having a proper metrics for such CGA grammars, we will be able to generate new virtual buildings of certain architectural style and to control their possible transitions among distinct styles.Categories and Subject Descriptors (according to ACM CCS): I.3.6 [Computer Graphics]: Methodology and Techniques-Languages, I.3.7 [Computer Graphics]: Three-Dimensional Graphics and Realism-Virtual reality
