A Part is The Central Idea or Concept of a Building.
The Parti is the diagramming of the essence and the core idea of a design agenda. The diagram can vary from a single diagram to a series of diagrams. Core ideas and agendas can be circulation, massing, programming, site relationship, public/private relationship, solid/transparent and many more. These diagrams help your panel and your audience understand your core ideas at a glance. The Parti diagram is a powerful tool in distilling the very essence of your ideas into one clearly understandable diagram.
