Our unfinished basement has 6 ugly, fixed windows that are covered with some kind of white plastic, added by the previous owners, and metal mullions that needed some work. One of these windows is visible from the back yard and it's appearance really bothered me.
We discussed painting the mullions and removing the white stuff but we didn't want people to be able to see inside, so I came up with the idea to put some kind of window shutter over it.
Once it was up like we wanted, I used some dark walnut stain and added some faux hinges and a lock to make it look more authentic, even though it doesn't open and close. A free and easy fix for one o our unsightly basement windows.
