Which of the following best defines a floor plan?

• A. A drawing that shows exterior and interior walls, doors, windows, patios, walks, decks, fireplaces, stairs, mechanical equipment, built-in cabinets, and appliances, shown to scale.
• B. A map of the land
• C. A drawing of electrical circuits only
• D. A schedule of materials

Answer: (A)

A floor plan is a scale drawing that lays out the arrangement of a building as seen from above. It shows how spaces relate to each other by depicting interior walls, doors, and windows, along with the placement of features that define rooms and circulation—stairways, fireplaces, built‑in cabinets, and appliances. It may also include exterior elements like patios, walks, and decks to show how the building sits on the site. The scale ensures everything fits together accurately for planning and construction.

This description matches the best because it covers both the interior layout and the key features that define a space, all shown to scale. Other drawings focus on different things: a map of the land is a site or plot plan, a drawing of electrical circuits is a wiring diagram, and a schedule of materials lists items rather than showing spatial relationships.
