Which activity initiates space planning with bubble and adjacency diagrams to analyze space relationships and circulation?

• A. Block Planning
• B. Space Planning
• C. Programming
• D. Diagramming

Answer: (D)

Diagramming is the activity that starts space planning by using bubble diagrams and adjacency diagrams to explore how spaces relate to each other and how people will move through the layout. Bubble diagrams quickly sketch spaces as simple shapes and show which rooms should be near or connected to one another, while adjacency diagrams formalize those relationships and the desired proximity. This approach emphasizes flow and relationships over exact sizes, laying the groundwork for the overall organization and circulation pattern before moving on to more detailed layout work. By focusing on how spaces relate and how movement occurs, diagramming sets up a coherent framework that later steps—like block planning and actual space planning—build upon.
