An inquiry on the formal generation of contemporary courtrooms and courtroom-aggregations based on existing project designed by eponymous architectural firms including Morphosis Architects; Safdie architects; Richard Meier Architects; and Scogin and Elam Architects. Details about the secure network of all these courtrooms are conjectured as long as the actual data regarding these parts of the courthouses are not generally available to public. All the courtrooms are represented in an identical manner using similar conventions of wall configuration, programmatic adjacencies, entry sequences, lighting conditions and so forth. Each courtroom is captured by a grammar that can produce more courtrooms in the same language too and all grammars can be combined in a variety of ways to produce new and interesting examples of hybrid designs. Similarly all grammars are extended to capture the ways courtrooms combine to produce courtroom aggregations, the core of courthouses, and significantly, all these grammars combine too. Two productions of the grammar– one to reproduce the original one (and verify the theory – the grammar) and another to produce a new diagrammatic representation are given for each language. The derivation of all designs is fully executed in an automated way in a shape grammar interpreter (Grasl and Economou, 2013).
