Envelope for garage under duplex
Planning a PGH, all electric, duplex on a small lot in Zone 6 Whitefish, Montana. Lot size/setbacks dictate that the two-story duplex with shared wall sit on top of the two-car garages. A scan of info from this site would indicate the garages be designed within the thermal envelope, as opposed to the envelope border being the ceiling of garage/floor of first floor. Any suggestions for a less expensive way to design the envelope than including the garages?
