With his "Weltkonstruktion" publication, Sascha Roesler offers the first global history of architectural ethnography (conducted by modern architects). The publication goal was to document the relevance of this history for today's constructive thinking in architecture. The modern architects' empirical exploration of domestic buildings outside Europe uncovered the narrowings of modern concepts of construction and made visible their epistemic limitations . In the ethnographic discourses about popular building outside Europe, parameters related to building that the architecture discipline - owing to time constrictions, or theoretical and ideological reasons - had neglected, may reconsidered again. In lieu of construction's usual orientation towards load-bearing structures, novel conceptual fields of reference appear, highlighted as thermodynamic or symbolically structured materiality.
