Technological development has played a significant role in architectural design throughout history. Nanotechnology is a rapidly developing field of technology with numerous current and potential applications in architecture and building construction discipline. It can promote architectural creation through forth ways affecting many aspects of architectural design; such as architectural thinking, structural design, building material applications, and construction process. The aim of this paper is to investigate the effect of technological development on architectural design, from the view point of form and shape, through two parts; the first part represents a literature review of the architectural history and technological development, and the second part investigates the more recent technological development represented in Nanotechnology as a concept, nanomaterials and new construction method, that has a wide effect on architectural design producing a new style of architecture called nano-architecture.
