Which wall divides spaces within a structure into smaller rooms?

• A. Partition Wall
• B. Division Wall
• C. Party Wall
• D. Fire Wall

Answer: (A)

Interior walls that split a building into separate rooms are called partition walls. They establish the individual spaces like bedrooms, offices, or living areas, and are often non-load-bearing, making it easier to modify or reconfigure the interior layout. A fire wall, on the other hand, is designed to resist fire and separate compartments to slow spread; a party wall is a boundary wall shared between properties or units; and division wall isn’t a standard term used for interior subdivision. So the wall that most directly serves to divide spaces into smaller rooms inside a structure is the partition wall.
