A floor plan is a drawing to scale that depicts the relationships between rooms, spaces, traffic patterns, and other physical elements at one level of a structure from above in architecture and building engineering. To indicate room sizes and wall lengths, dimensions are frequently drawn between the walls. The technology symbols in the floor plan include home appliances like coffee maker, washing machine, water heater, etc. Use these symbols to locate the electric appliances places in your house and to arrange the best place to put them. It would be helpful when considering how to wire the house based on the locations of home appliances.
