You will need a house to unwrap the things and push them out, because non-walkable objects since 2007 aren't allowed to be carried into your backpack, (back then only a pot was possible)
Then you will need a box any kind of box or a crate, you fill it with trash, then you place your non-walkable object on top of that 1 or 2 boxes filled with trash, then you browse field and you proceed to break the box, when it does all the trash will go on top of the non-walkable object, thats how you build your invisible wall.
The effort isn't worth because a single disintegrate rune will make your work disappear.
Enjoy
