Here's the top view of my company. In architecture and building design, a floor plan is a drawing to scale that illustrates the relationships between rooms, spaces, traffic patterns, and other physical features at one level of a structure from above. Dimensions are usually drawn between the walls to show room sizes and wall lengths. Floor plans may also include information about equipment such as sinks, water heaters, and furnaces. Floor drawings may show construction details such as finishes, construction methods, or electrical device symbols.
