Concept Design

Comprehensive knowledge base for architectural concept design including parti development, massing strategies, spatial organization models, concept-to-form translation, and design iteration protocols. Invoke this skill when developing early-stage design concepts, evaluating massing options, organizing spatial programs, or translating abstract design ideas into architectural form.

Section 1: Parti Development

1.1 What is a Parti?

The parti (from French "parti pris" — a decision taken) is the essential organizational diagram of a building. It is the irreducible idea that governs the relationship between program, structure, circulation, and site. Every design decision should be traceable to the parti. If a move does not reinforce the parti, it weakens the design.

A strong parti:

• Can be drawn in 30 seconds with a single line or simple shapes
• Explains the building's organization to a non-architect
• Resolves the primary design problem (access, view, climate, program)
• Generates both plan and section logic
• Remains legible in the finished building
