This communication puts into perspective a decade of architectural experimentations dedicated to the morphogenesis of atmospheric environments. Through the process of designing, manufacturing, building on site and evaluating some micro architectures or pavillions, I propose a research by design that offers a new direction for architectural research, specifically in the field of ambiances. While being attached to an ecological perspective, I use contemporary digital technologies that involve a revolution in design practices and architectural innovation. More specifically, the emergence of parametric modelling tools associated with CNC machines enable the work on ‘non-standard’ architectures, which renew the aesthetical approach of architectural experience.
