You can never have enough storage in the kitchen. If you lack cabinet space but have just enough room along an area of a wall, an armoire can serve as a wonderful pantry. Check out this great example from Decoholic. Alternatively, you could use the same idea as above, but for coffee instead. Ever Evolving Life 4-5 shows the complete transformation this armoire went through to become a cute little coffee bar.
An armoire can be a lovely addition to your bedroom, even if you already have a giant walk-in closet. If you have enough stuff, you may want to dedicate your armoire to neatly organizing and storing all your jewelry, scarves, purses, handbags, shoes, and other smaller accessories. Do you own enough hats? Simply replace the glass doors with netting for an interesting way to display them.
