4/ A Guest Room
Rather than constructing an extra room for yourself or your family, why not turn it into a guest room? You may decor it with one or two beds to accommodate a short a long term stay. Make sure your guess room will follow your home's current style.
Plus, if you need some alone time, you can always run up there for the night. Furthermore, you can twist it up and create a one-of-a-kind style for your visitors. Some extra research should give you an idea on which types of guest spaces are preferable by many.
