Wall

A wall is a usually solid structure that defines and sometimes protects an area. Most commonly, a wall delineates a building and supports its supestructure, separates spaces in buildings into rooms, or protects or delineates a space in the open air. The presenters explained to us the meanning of bearing walls and non-bearing walls. Bearing walls are those that carry load or helps the structure of the building, and non-bearing walls are those that don't carry any load, their principal function is usually sthetics or separate spaces. Also we learned a little about retaining walls, which are in the category of bearing walls beacause they are the walls that may be either external to a building or part of a building, that serves to provide a barrier to the movement of earth, stone or water.
