Hope I can explain this well enough to illustrate the issue. (adding images)
There is a main living area with vaulted ceilings
There is an addition (screened-in porch) with a full gable wall
I'd like the main living area to have the vault from the main roof...but the gable wall addition is carving out it's own vault.
I'd like the "V" in the main space to be vaulted per the main roof area...not having a niche ceiling carved out because of the addon porch.
Ideas/help? Thank you for your time!
