Closing in part of the front porch wiith acess from the window opening sounds like a good plan. Since the window is already there you will not have to do major construction for a doorway. The header should already be there. You can either use a retrofit French window that you can step through or replace the window with a double paned garden door (not a slider). Then put in screens around the porch area, and glass it in with removable windows for winter. Instant greenhouse in winter and screened porch in summer with LR access. Using a glass door you can have the view of your flowers and plants.

and then I stopped at the house to crate the chickens, and change out of the barn boots, and met them at the little local rest. to eat. Then came home.
