This would be perfect in our kitchen! One pantry could be for the larger cooking appliances---crock pots, pots, pans, etc.---and the other for food! Imagine how much space that would free up in the wall cabinets.
Shallow floor-to-ceiling pantries - an efficient use of an interior wall, where you can't have a window anyway. By limiting the depth to just 6 to 9 inches, you are forced to line up your dry goods in a single row, making everything easier to find.
