So the plan is to remove the planter, build a wall on the side where the planter is Relocate the entrance door. Practically this turns the porch into a entrance hallway. The porch has light on the ceiling, controlled from inside. The porch is built on a concrete slab that you can see in the picture. I am inclined to believe that it has a proper foundation and it won't need to rebuild it. I will have to remove the tin ceiling of the porch and install drywall and insulation there. I might choose to leave the brick look of the wall adjacent to the garage (left side of the picture) and insulate that section of the wall from inside the garage.
What am I missing or overlooking. For those of you who want to make references to the code this is in Ontario Canada
