I am a new home owner. I have a 3 car detached garage and a 2 car attached garage. I want to make the attached garage into living space. Currently it is attached to my living room so I think I just want to extend that space. I know there has to be more than just knocking down a wall, replacing the garage door and extending the heating and air capacity but I haven't a clue as to how to begin or where to begin. Anyone that has done this, please email me and tell me of your experience. Or just tell me what all to consider. Thanks a bunch!!!
