Definition of ground plan

The origin of the term "ground plan" can be traced back to architectural drawings. A ground plan, also known as a floor plan, is a visual representation of a building's layout as viewed from above. The phrase "ground plan" likely originated in the 17th century when architects began creating drawings of buildings to communicate their designs to clients and contractors. By viewing a building from above, architects could more easily explain the location of rooms, doors, and other features, particularly as building designs became more complex. In ancient times, architects relied on physical models and written descriptions to communicate their designs. However, as buildings became larger and more complex, it became increasingly difficult to accurately convey information about the layout of a building. To address this issue, architects began creating scaled-down, simplified drawings of their designs. These simplified drawings, known as plans, showed the layout of a building, including the location of walls, doors, and windows. By the 17th century, architects had begun using the term "ground plan" to specifically refer to diagrams of the ground floor of a building, as this level was considered the most important and served as the foundation for the rest of the building. In summary, the term "ground plan" was coined in the 17th century as a way to communicate the layout of a building more clearly to clients and contractors. It refers to a drawing or diagram of the layout of a building as viewed from above, particularly the ground floor. The use of ground plans has since become an essential part of architectural design and communication.
