An overhead diagram showing a view of the structure's walls, doors, and stairs is a:

• A. Plot survey
• B. Sectional view
• C. Plot plan
• D. Floor plan

Answer: (D)

An overhead diagram showing walls, doors, and stairs is a floor plan. A floor plan renders the building from above on one level, highlighting how spaces relate to one another, where walls sit, where doors swing, and how stairs connect different areas. It’s the view you use to understand room sizes, flow, and the organization of the interior.

A sectional view, by contrast, is a vertical cut through the structure that reveals heights and vertical relationships—ceilings, floors, and stair details along a cross-section. A plot plan shows the building’s footprint on the site with property lines and surrounding features, not the interior layout. A plot survey focuses on land boundaries and measurements, also outside the building rather than the interior arrangement.
