Creativity is a fundamental topic of study in design, encompassing the formation of new ideas and insights. As such, creativity is critical to the development of innovative cognitive processes, as well as the development and production of innovative outcomes at the abstract, configurational and detailed levels. The objective of this Special Issue was therefore to explore how creativity can be characterized and supported throughout design activity in architectural and engineering domains related to construction and built environments. Five core papers were originally published, with contributions from an international spread of researchers, including Lithuania, South Korea, Israel, Australia and the UK. These encompass considerations of social context, visual communication, creative spaces, decision-making and computation support.
