I just bought my first home and I have a 2 car attached garage (attachs to the living room) and I want to knock out the living room wall and convert that garage into more living space. What all should I consider? Anyone know about the expense of this project? I have seen someone do this and replace the garage door with French doors and I thought it looked like a refinished garage. I think I would want to extend the brick and have a large window installed. Any suggestions?
