A wall is an architectural partition used to divide or enclose an area. Walls may be load-bearing or non-load-bearing.
A load-bearing wall is part of the structure of a building and supports additional floors or the roof. Non-load-bearing walls are simply to divide a space into smaller spaces for specific uses. They may be altered or removed without affecting the integrity of the structure.
To allow passage through a wall, a doorway or archway is often utilized.
