What type of plan shows the external face of a building at a set scale?

The term that refers to a drawing showcasing the external face of a building at a specific scale is known as an elevation plan. An elevation plan provides a vertical depiction of a building's facade, illustrating elements such as windows, doors, materials, and architectural details from a frontal or side perspective. This type of plan is crucial for understanding the appearance and design of the structure from different viewpoints, informing both construction and aesthetic evaluation.

In contrast, a floor plan primarily focuses on a horizontal layout of the interior spaces, indicating walls, rooms, and layouts as seen from above. A foundation plan details the base of the structure, including footings and support elements, while a plot plan provides an overview of a piece of land, including the layout of the building on the property and any surrounding features. Each of these plans serves specific purposes, but only the elevation plan effectively represents the external visual characteristics of a building.
