Question

The usable area of a floor is called:

• A. Carpet area
• B. Plinth area
• C. Surface area
• D. Built-up area

Hint:

When asked about usable living space in buildings, the answer is almost always carpet area.

Answer 1

The Correct Option is A

Concept: Different types of floor areas are defined in building planning to distinguish between usable space and structural or circulation spaces. Explanation:
Carpet area is the net usable area within a building, measured from wall to wall.
It excludes wall thickness, balconies, corridors, staircases, and other common areas.
Plinth area includes carpet area plus wall thickness and other covered spaces.
Built-up area further includes balconies and external walls.
Surface area is a general term and not specifically used to denote usable floor space. Hence, the usable area of a floor is called carpet area.
Final Answer: \(\boxed{\text{Carpet area}}\)
