Yes, and yes, Mary. My garage is unheated. It is far easier and more economical to heat a 6'x10' insulated structure than a (mostly uninsulated) space that is 3-4 times as large. My garage is an oversized, two-car garage. We have garages down here to keep our autos out of the weather, for (secure) storage, and for security. There are lots more reasons to have a garage space.
