Architecture - considered as a built environment - affects all areas of all human life. However, the consciousness towards constructed spaces is lacking, which is a fundamental flaw. Understanding architecture helps laypersons for stating needs, improves architectural design and saves resources. This master thesis sets out to a quest, looking for reasons of this knowledge gap among widespread populations in Austria. It analyses current and historic architectural communication projects at Austrian pedagogical-based institutions and international art projects in public spaces. As first step, these projects are divided in two categories: top-down and bottom up. Then, their potentials, methods and reach are determined. Furthermore, it identifies the core issues of the covered projects. Comparing them shows that background knowledge and high interest is required among involved players in order to carry them out or participate. That-s why they do not work -for everybody- and seldom reach many target groups. As final step, the results are used to compose a communication strategy named space+sense, which webs this thesis- findings together. Experimental, urban interventions are unified with existing concepts and projects to a brand and platform, which supports the exchange between citizens, intermediaries and planners. Playing as a daily experience is an essential part of it.
