In my vacation home have a loft area that I want to use as storage. Because I rent out this house I want to be able to install a door with a lock to prevent tenants from entering the storage area. My problem is that the opening to the loft area is narrow and tall. Someone suggested an accordion door but I don't see how I am going to be able to lock that type of door. A pocket door won't work either as the entry way is on an angle with the wall. I'm considering a custom made door but worry that a door frame would make the doorway even more narrow than it currently is. I'd even consider some type of door or gate with a padlock as long as it secures the area and looks okay. Looking for suggestions on what type of door would be best for this project.
