Adapting cellular automata to support the architectural design process

Abstract

This paper investigates the support of generative architectural design processes using cellular automata systems with a high level of involvement of human designers. Previous applications of cellular automata to architectural design have oftentimes been characterised by their limited generative capacity for top–down developmental control and for pragmatic rule-breaking as they are easily offered by human designers. This paper explores different options for modifying and extending classical cellular automata systems to support architectural form finding. It discusses the potential of cellular automata as generative design tools with respect to the questions: In which part of a design development, during which periods during a design process and in what roles do cellular automata promise desirable results from a practical standpoint? In response to these questions, a theoretical framework for the integration of cellular automata into the design process is presented. An implementation of a dialogue-based cellular automata-supported design process model is outlined and evaluated by remodelling an existing architectural design project.
