I could make a list of regrets for my house I built five years ago. They all have to do with things that cannot be changed now. They include not insulating under the slabs. The garage heat isnt one of them. I have an attached garage with a hanging modine heater and I like being able to quickly raise the temp in there. After the barn is built I see me using this only occasionally. We use the attached garage for parties as much as for working on stuff.
