We have high ceilings and tall doors out here in Bullhead City, AZ. I am removing the 95" high exterior door off of our patio and replacing it with a standard 80" prehung exterior door that is all solid and better as far as security seeing as the other door is all glass. so my question is, with the extra 15" I will have at the top of the new door, I want to put in a window,how do I go about framing in for a window in that extra 15" space, I want to get this done b4 our 117 degree summer gets here, I would appreciate some help. Thank you.

The two methods are to either frame in above the door framing for a window or get a door with an attached transom. Since you have already purchased a standard door, looks like you are going with option #1.

You can do whatever you want with the framing to make it fit the window you choose. Your load bearing header is up above the top of the window area so any framing to separate the door from the window will be strictly on a 'whatever you need' basis. Probably the hardest part will be finding a window to fit the space. Decide if you want an opening window (awning) or a fixed glass panel. If you can't find a standard size to fit the new opening, you'll need to get a window custom made.

Beyond that, it's a matter of installing the new window in your new rough-opening, insulating around it and trimming it out.

Look into a Transome window as Jaybee suggested, looks great, more light in the room, simple to add.

I think you should install Impact windows above the door to fill that extra space. It will give an extra exquisiteness to your door. Best thing about impact windows is that these are quite easier to install at any place in your house.
