In architecture and building engineering, a warehouse floor plan is a drawing to scale, showing a view from above of the relationships between rooms, spaces, traffic patterns, and other physical features at one level of a structure. A warehouse floor plan design starts with understanding dimensions as it plays a critical part in the warehouse floor plan and before one gets into individual elements like storage areas, packaging areas, inventory, transport, and information and control. By creating a warehouse floor plan flyer, a designer can scale drawings that will provide a way to visualize how people will move through space. A warehouse floor plan design and space planning are essential in new structures, but it is also essential to rethink existing spaces to use them efficiently.
