What is the function of a floor plan?

The function of a floor plan is to show the layout of rooms, walls, and doors within a building. This type of plan is a flat representation of the building viewed from above and is essential for understanding how different spaces are arranged in relation to one another. By using a floor plan, builders, architects, and homeowners can visualize the flow between rooms, the division of space, and how the overall design will function in practice.

In addition to the arrangement, floor plans often include dimensions, which are critical for ensuring that spaces meet required size standards and that furniture and fixtures will fit as intended. This clarity aids in planning, construction, and communication among all parties involved in a project, from design to execution.

Other choices refer to specific aspects of building design, such as plumbing, structural systems, or landscaping, which are not encompassed by a floor plan. These elements may be part of larger architectural drawings or separate plans but do not define the primary role of floor plans themselves.
