The concept features as a vital element in architectural protocol and its vocabulary. If architecture and philosophy are defined as creation of concepts, then they are the terra nullius shared by both disciplines. By distinguishing the architectural concept from its philosophical counterpart, this paper analyzes the former as an entity that animates and directs a project as the documental prefiguration of an architectural object. In a more radical move, we consider architecture itself as a concept, that is, what makes architecture (...) what it is and what this discipline can become tomorrow. In addition to decisively participating in the process of generating an object yet to be constructed (the fetus of a building), on a correlative level, the concept has an essential role in theoretical self-thematization of architecture and guards the future of the architectural profession as an autonomous intellectual discipline.
