Which term marks the preliminary design phase by illustrating the physical boundaries of functional spaces and circulation, while involving conceptual thinking in space planning?

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

Answer: (A)

Block planning is the step where you sketch the large, physical outlines that define where each functional space will sit and how people will move through the layout. It focuses on the footprint and the circulation pattern, using broad blocks to represent rooms or areas and the paths that connect them. This approach requires conceptual thinking about how spaces relate to one another, which is exactly what happens in the early, preliminary design phase of space planning.

Think of it as drawing the first skeleton of the plan: you decide which areas should be near each other, where corridors or routes will run, and how the overall flow will work, without getting bogged down in exact measurements, details, or finishes. Programming would come earlier to establish needs and requirements; diagramming would map relationships and flows more schematically; space planning would proceed later with more detail about how the interiors are organized. The emphasis on establishing boundaries and circulation in a conceptual way is what makes block planning the best fit for this description.
