House floor plan with 2 bedrooms shows here. A floor plan, on the other hand, is essentially a simple graphic that shows room layout and serves as a conceptual starting point. Space planning is crucial in new construction, but it's also important in considering existing areas to see how they might be used more efficiently. The view is downward from above, similar to a map, but unlike a traditional map, a plan is created at a specific vertical point (commonly at about four feet above the floor). Objects below this level are visible, objects above this level are shown 'sliced' in plan-section, while objects below this level are hidden.
