You can modernize an old-looking closet by just painting it, but beyond that, consider electric elements like recessed or accent lighting. If this is a large and deep closet, you can consider adding an island to the middle or a nice ottoman on a rug. Luxury closets will have even more items, like felt-lined drawers for watches and jewelry, in-wall safes, electronic shoe storage, or a tablet catalog of their items.

The features you choose for your laundry room to make it perfect depend largely on how you'll use the space, the size of your family, and their laundry needs. A perfect laundry room will have ample storage space, a clothes washer and dryer that are large enough for your needs and have good convenience features, and enough room to move around and work with enough countertop space to make laundry chores as easy as possible. 

There are certainly luxury upgrades you can make but you can seriously improve the look and functionality of a closet without spending much money. Color matching will make the closet seem bigger so any shelves painted the same as the wall is a good tip. While pre-made closet organizers may seem expensive they offer an aesthetic look that's hard to achieve with DIY methods. Lastly, removing clutter and unworn items will help the closet seem bigger and cleaner.

Walk-in closets are always the biggest and can easily be more than 100 square feet. Primary bedroom closets, even if not walk-ins, are the second largest category in most homes and sit between 30 and 80 square feet. Linen closets, utility closets, and built-in closets are smaller and, depending on their usage, tend to be between 10 and 50 square feet.
