I have a single story home with an attached garage, but built like a 2 story. The whole upper half of the house and garage are open in an attic space. To me this is such a waste of space. I would love to turn this wasted square footage into living space. My question is where do I start to make this possible? Architect,handyman,contractor....etc. Whom do I contact to see if this is even a possibility?
