Making a plug to put in place of the front window, now a kitchen wall and the front entrance now becoming the back door.
Here's the view from outside, with the bottom and one upper window filled. This window on the second floor was the one giving me the most grief, as there were 5 cutouts and I only have 4 windows. I'm not sure if I've thrown it off balance now. Possibly turning the existing window into a door and adding a balcony might look better. Which would leave me then with an extra window.
With the front door now becoming the back door, I needed a new front door. I didn't have a window for this side so I closed in the door and cut the existing window out for the new door with sidelights.
What's the next step? I'm actually not really sure.
