A floor plan is a scaled diagram that represents the layout of a building or room from a top-down perspective. It shows the arrangement of walls, doors, windows, and furniture, helping to visualize how spaces are organized. Floor plans are commonly used in architecture and interior design to communicate design ideas and facilitate construction. These plans can vary in detail, from simple sketches to detailed blueprints. They are essential for understanding the flow of a space and can assist in planning renovations or new constructions. Floor plans are often created using software tools or by hand, depending on the complexity of the project.
