   I can't imagine why any builder would have a problem with it. 2 x 6" exterior walls. 24 oc aren't anything new. However, if it were my house I'd go with 16" oc and install foam board on the outside of the walls walls instead. You aren't going to get much bang for your buck your way. .

   When i built my house I looked into doing 24" on center.  Some building materials and siding will allow 24 OC, but many specify 16 OC maximum.  I wound up doing 2x6, 16 OC, and 3/4 inch foil faced poylcio on the outside.  The foam on the outside breaks the thermal bridge of the studs, and i didn't have to worry about what I planned to use for siding or interior finishing now or in the future... You would have plenty of structural strength with 24 OC, but you may live to regret your decision when you start looking at materials and what you really want isn't rated for 24 oc framing.

   I'm not sure where you are but 2x6 24" o/c is pretty routine here (Winnipeg, Canada). I just built a house using that AND 2" of ridgid foam on the exterior to break the thermal bridge (I got R30 (approx) in the wall) as a result and saved a bunch of time framing. No magic to it.

   If your builder won't do it have him/her wake up and see its 2011 :)

   Thanks

   I talked to my drywall sub today and we are going to stay with the 24" OC and 5/8 drywall.

   Don't forget to account for the extra thickness of the drywall when you order windows and doors.
