This course focuses on the development of the material and constructional idea of structure, substrate and skin through a focus on major material groups relevant to interior architecture and material selection as informed by aesthetics, functionality and environmental sustainability. Core considerations include structure, substrate and skin explored in reference to specific materials and conventional interior details with a focus on joinery and material finish; introduction to documentation as a means of technical communication to industry professionals and the role of the builder versus the role of the interior architect and the coordination between the two. Emphasis is on materiality and simple detailing through studio based exercises and precedent studies.
