Close half basement back door with concrete and window
I see your help if fast and promising with other topics. Hopefully I will get some good suggestions to my planned project. We have a split house. Lower level is half way underground. We moved into house 5 years ago and never used the back door. We use patio door on back side of the house on middle level.
So, I want to remove the door and replace it with window to have some light in lower room. The question is how to better close the lower part. Should I just build wooden walls and pour with quickconrete mix?
