A floor plan is a scaled diagram that shows the layout of a building or room from a top-down perspective. It typically includes walls, doors, windows, and fixed installations like kitchens and bathrooms. Floor plans help visualize how spaces are organized and how people will move through them. These plans are essential in architecture and interior design, as they guide the construction and arrangement of furniture. They can vary in detail, from simple sketches to detailed blueprints, and are used for both residential and commercial properties. Understanding floor plans is crucial for effective space planning and design.
