Hi, I'm designing a garage with an ADU above. There is a straight run of stairs from the garage floor level to the floor above. Access is from an outside entrance. There will be no access from the garage. I want the space below the stairs to remain open so it can be utilized in the garage, but want a wall to follow the slope of the stairs and connect with the ceiling above so the stairs are fully enclosed and separated from the garage. I have see references on how to enclose the space below a stairway, but not above. I hope I'm making sense to anyone who reads this. Any suggestions/direction would be greatly appreciated. Thank you!
