17 zu 7 - Der ideale Grundriss von Castel del Monte und seine Überarbeitung in der frühen Werkplanung

The Apulian Castel del Monte has a distinct floor plan that is based upon three concentric octagons. This is why the proportions of the floor plan are based upon the Silver Ratio. However, this proporational system requires measurements which have irrational numbers that are very difficult to work with on a construction site. For this reason, the design of the building was converted into a modular system during the early construction planning phase. The modular system operates with whole numbers while preserving the intended design concept. The ratio of 17 to 7 is of fundamental importance here.
