Like starshine said, for boars you need that space, because they have their moments when they are not such great buddies. I have a 2x4 for my boars, with two lofts. In those lofts I keep the food, and cozies where they sleep or hide, just to have space on that lower 2x4. The ramp takes a small space too where it reaches the floor, so you want to keep it as clear as possible for laps. I keep a box in which I carved 4 holes, one on each side, so my boars can escape from each other if they have to. And the hay too because they like it there.
