This paper is an overview of different approaches related to the study of design and Creativity in Architecture.Being wicked and ill defined,design problems led to over simplified models that could not deal with their increasing complexity.Many design models have been elaborated in order to deal with this complexity and to offer more creative possibilities.This study defines Architectural design as a dynamic and situated cognitive process of exploration and coherent treatment of information in order to generate a response to a problem.Architectural creativity is considered as a multidimensional process of reorganizing information and putting together models,following some specific rules that may have implicit the type of geometric patterns that emerges,in order to built solutions to a situation or a problem.This study is a theoretical background for future researches on the development of creative architectural design processes.
