The floor plan is the blueprint about the first floor. A floor plan is a scaled depiction of a room or structure as seen from above. The floor plan may illustrate a full structure, a single level, or a single room. It may also include dimensions, furnishings, appliances, or anything else required for the plan's purpose. Floor plans may be used to assist in the design of furniture layout, wiring systems, and much more. They're also a useful tool for real estate brokers and leasing firms when it comes to selling or renting out a property.
