Floor plans and site plans are similar but they are different. Site plans provide information on the areas of a plot of land beyond the boundaries of the building. A floor plan shows details and elements of the building up to the end of the structure. A floor plan is a drawing with the roof of the structure removed. It is the horizontal section cut through of a structure to show the inside view. Most of the time, floor plans and site plans are complementary of each other are used together to provide a full understanding of the interior and exterior of the structure being built.
