It would be better if you posted a picture of the area where you need the door.
Why would you use shutters and not just buy a bifolding door set for 1/2 the price?

Is this your home or are you renting?
To meet code if this area is open or used for storage it has to have 5/8 sheetrock on the underside of the stairs.
Most of the time I frame in a knee wall at the back of the area since it's usless for storage.
