An elevation drawing is a view of a building seen from one side. It is the two dimensional, flat, representation of one facade. It displays heights of key features of the development in relation to a fixed point such as natural ground level.
An Elevation is an image that shows the height, length, width and appearance of a building or structure. Elevations are drawn as if looking at a building from the front or side (as opposed to floor plans which are drawn looking at a building from above) and provide the viewer with an idea of how the final building will appear.
