A "parti" is a fundamental concept in architecture that represents the overall design idea or concept of a building. It serves as a guiding principle that informs the layout, form, and organization of spaces within the structure. The parti can be visualized as a simple diagram or sketch that captures the essence of the design. In architectural practice, the parti helps architects communicate their vision and intentions to clients and collaborators. It often reflects the relationship between different elements, such as light, space, and function, ensuring that the final design aligns with the original concept.
