What would you do with a 7,000 square foot house? Who could possibly use all that space?
If you're Paris Hilton, you need it. You have to find someplace to house all your clothes.
The $5.9 million mansion comes complete with 5 bedrooms, 5 1/2 bathrooms, and a fitness room. However, Paris apparently gets enough exercise walking around her enormous castle, so she's converting the fitness room, so she's converting into a closet for her shoes.
I'm sure she'll take the study, or the library, or a couple of the bedrooms, and use those to house the rest of her wardrobe.
