Build a Second Floor
Adding a second story can do more than just create square footage. It can bring balance to an uneven house. A flat roof over a garage can be an eyesore as well as a huge waste of space. You could solve both problems at the same time by adding on to the top of the garage. Use all that dead space to build a master suite or a reading room. You will not only add space, but you will also add tremendous curb appeal.
