I have come to the stage in my work on the basement when I have hinged the fronts. Fronts allow some additional space for display; you can even make a separate fake room. For the basement, I have chosen to have natural fourth walls. But this is the last and only time when these can be viewed as walls, from this angle:
When I have put on the roof, the only way to see the fourth wall will be when the front is open:
The wall allows to display the array of kitchen utensils I made eight years ago for my very first kitchen (so far, white-tacked). I am still very proud of them. This way, you can see them much better than inside a crammed room.
