A floor plan is a scaled drawing of a room or structure as seen from above. A floor plan might show a whole structure, a single level, or a single room. It might also contain dimensions, furnishings, appliances, or anything else that is relevant to the plan's goal. Floor plans are important for a variety of purposes, including furniture placement, wiring systems, and more. They're also helpful to real estate brokers and leasing firms when it comes to selling or renting out a place.
