Why not have shelves and open storage space in the kitchen that reaches the floor? Makes use of space that standard units do not fit and is flexible storage and display use, for everything from pots and pans to cookery books and vintage display finds.
IKEA shelving - add pegboard to the sides for extra storage. if what you put in here isn't this pretty, hang curtains to hide them. This will expand to whatever size you need. Or use heavy-duty shelf units made for garage use & disquise as above.
