Steps:

1. Draw lines down the exterior wall, directly below the edges of the window to have a guide to cut by. Start demolition from the outside in order to check for any electrical wiring or other obstructions.

2. If cutting through vinyl siding, place the circular saw blade on backwards to prevent excessive damage. Cut through the siding, following the lines drawn on the wall.

12. If necessary, build steps to lead up to the door. Measure the step tread in order to figure out the spacing of the pre-cut stringers. Once determined, nail the stringers into the wall for support.
