The implantation area is the area located within the perimeter of the building's fixation to the ground measured from the outside, including the area occupied by porches and sheds with pillars fixed to the ground.
The area of sheds and porches does not, however, include the dependent gross area, as it is not a closed area. When the cellar area extends beyond the main body of the building and its roof is above ground level, this area also integrates the implantation area.
