Which plan type shows external walls, internal walls and partitions as part of the layout?

• A. Floor plan
• B. Site plan
• C. Elevation
• D. Profile

Answer: (A)

The main idea here is understanding what each plan type conveys in a building drawing. A floor plan is a top‑down view of a single level that shows the arrangement of spaces and how they are divided. It includes the outer boundary walls (the building envelope) as well as interior walls and partitions that define rooms, hallways, and other spaces. This horizontal slice lets you see how rooms relate to one another and where doors, openings, and corridors lie.

A site plan, by contrast, shows the building in relation to the property lines, access, parking, landscaping, and other site features. An elevation presents the vertical exterior faces of the structure, showing heights, materials, and architectural details from the outside. A profile is a vertical cross‑section through the building, displaying how spaces stack and relate in height.

So, the plan type that includes external walls, internal walls, and partitions as part of the layout is the floor plan.
