I have a large upvc window with a small upvc window above (which opens). I would like to remove the larger upvc window and the wall beneath it, and put in french doors of the same width (4ft) - (opening into a back yard).
I would like to leave the small window in place and fit the door under it- since the room needs as much light as possible.
Would this be a possibility or would I have to buy purpose built french doors with a window on the top?
