In architecture, a parti is an organizing thought or decision behind an architect's design, presented in the form of a parti diagram, parti sketch, or a simple statement.[1][2] The term comes from 15th century French, in which "parti pris" meant "decision taken."[3]
The development of the parti frequently precedes the development of plan, section, and elevation diagrams.[4]
History
Producing a quick sketch (esquisse) of the parti was a critical part of architectural training at the Beaux-Arts de Paris during the 19th and early part of the 20th Century.[5]
In architecture school during the 1900s in the United States, one would have understood the term ‘parti’ as the "main idea" for the planimetric layout of a building. Its roots in the American architectural education system are derived from the Beaux-Arts de Paris. The word "parti" refers to the concept of ‘parti pris’, and refers to the main ‘idea’ of the organizing principle that is embodied in a design and often expressed by a simple geometric diagram. The "parti" often expresses the essence of an architectural design reduced to its essence.[6]
^"A primary protagonist was Rudolf Wittkower, who had published important essays on role of geometry in the works of Alberti and Palladio, essays later collected in Architectural Principles in the Age of Humanism (1949, 1962). The book includes Palladio's Geometry: the Villas, in which Wittkower argues that similar organizational schema underlie all the villas of Palladio. Wittkower's diagrams of the villas are variations of a three-bay by three-bay diagram; a nine-square grid. Wittkower suggests that Palladio's villas can be considered as a single conceptual project based on variations of an ideal plan diagram: “What was in Palladio's mind when he experimented over and over again with the same elements? Once he had found the basic geometric pattern for the problem ‘villa,’ he adapted it as clearly and as simply as possible to the special requirements of each commission. He reconciled the truth at hand with the ‘certain truth’ of mathematics which is final and unchangeable.”
