As shown in the Aman Floor plan diagram below, a floor plan is a two-dimensional drawing to scale that shows an area from above. While creating a floor plan diagram of your preference, you will learn that it indicates the relationships between rooms on one level of a structure, and it can also be used to describe buildings to those involved in the construction process. It should be noted here that there are three different types of floor plans, traditional, contemporary, and custom. Here, traditional floor plans would tend to have more walls throughout the house; contemporary plans are more open and spacious, and custom plans are whatever is required by the client.
