I try not to wear a tin-foil hat too often or worry about how long it will take the zombies to reach my house during the apocalypse, but I do like knowing that there's enough food in the house to feed us for more than a day or two. When we first decided that the little 'pantry' in the kitchen was way too small, it was time to consider where to set up some additinal food storage space. On the lower layer on our split foyer, between the garage and the family room, is an unfinished area that houses the furnace, a powder room, the sump pump and the washer and dryer - we just call it the back room. Since the room is unheated and is closed off, we decided that it would also serve well as a food storage area. It's also cool and dark which is a real plus.
The shelving unit is barely a foot deep so it still allows to easy passage in the area and everything is easily accessible. We got the shelves at IKEA so they were very reasonably priced and went together quite easily.
The picture at the right shows them after assembly still sitting upstairs in the living room. Not shown is the fifth section that joins the two parts that we assembled first. The back room is an "L" shape and not terribly wide so we figured it would be easier to put four of the five sections together first where we had more room and then connect them together with the fifth unit downstairs.
There is something rather comforting about having a decent amount of food in the house, and in the years since we've added the storage shelves, I've really come to appreciate the convenience of having ingredients on hand. Since we live about 7 miles from the closest grocery store, it makes more sense for us to buy many items in bulk. They're usually cheaper that way and it definitely saves time and gas not having to run to the store as often. We also have a full size freezer that gets plenty of use as well, though I prefer to store canned foods more than frozen, just in case the power goes out for any prolonged period.
