Walls

A wall is a vertical structure that forms the perimeter of a building or other enclosed space. Walls are typically made of wood, brick, concrete, or plaster, which are used to provide support, protection, and separation. Walls may be load-bearing, which means that they support the weight of the structure above them, or they may be non-load-bearing, which means that they do not carry any weight and are used for decorative or functional purposes. Walls may also have openings, such as doors or windows, which allow people to enter or exit the space.
