If I rent a loft bed in Nugent Hall, can I move my desk under my loft bed? If I can, should I? I’m aware that it may block some in-wall shelving and it could be valuable storage space for me.

Yes, you can fit the desk under the loft bed. In Nugen, in-wall shelves are only at one side of the room, you can lean your bed on the other side and don’t need to worry about wasting storage space.
