One thing to consider is location and stored item needs. If some preps keep fine in the heat and without AC for example, can put them someplace like the garage/attic, etc., saving space indoors for food items, etc. that keep better with some climate control.
If you have an attic, even a small one, don't forget it as a place for storage.
