My oversized double insulated garage is actually my cave man that I share with the 911 and has been doubling up as my day office for the last 2 years..
I got the oil radiator on timer (05:00- 16:00), a hanging square box heater kept at minimum overnight that I crank up 30 minutes before going in, a electrical fireplace for ambiance and I ran a vent from the house.
Yes, yes bylaws crapola... The 911 is rolled out 20' down the driveway before its started so the only obnoxious odors is when I let go one
