Which of the following is a horizontal drawing of a structure at a given level such as ground floor, basement, or roof?

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

Answer: (B)

A floor plan is a horizontal drawing that shows the structure at a specific level by looking down from above. It captures the layout of rooms, walls, doors, windows, stairs, and fixed features on that level, often with room names and dimensions. This perspective is used for understanding how spaces relate to one another on that floor—whether it’s the ground floor, a basement, or the roof (a roof plan is simply a floor-plan view drawn at the roof level). Elevations are vertical views of exterior faces, and sections are vertical cuts through the building, so they don’t provide the horizontal, level-by-level view that a floor plan does. A site plan shows the building’s footprint on the site, not the interior layout.
