The 2B studio is the fourth in the sequence of seven studios that constitute the core of the undergraduate B-Arch curriculum. It follows the lessons of previous semesters by designing material form (Massing/Interiority) in close relationship to techniques of drawing and modeling. This studio expands from building massing models to constructing materially specific models that emphasize building systems that are necessarily composed of parts rather than wholes. This shift addresses material constraints—such as size and thickness, structure, and finish—which, in turn, produce interesting limits and problems of translation between digital and physical media. I engaged the reading on theories of cladding, from Semper to Loos to the present day, and discussed the role of ornament and material effects through rendering, physical model making, and specification writing
