Do you have extra rooms in your house? What are you doing on it? Do you put some things in it or you just leave it bare?
There are many advantages of having an extra room in the house. You can turn it into a guest room; you can have a space for emergency purposes, and temporary storage of your things. The extra room can be considered an asset if you can use it for a purpose. However, if the room is left bare and without a purpose, you have to start thinking what to do with it.
