We are putting the kibosh on the barrel ceiling in the foyer. It was going to be something like the photo below (going from 10' to 11'). The dimensions are 17'5" x 8'6". Now we are doing a flat 10' ceiling with cove moulding like the rest of the house. By making that change from barrel to flat, what would you roughly guesstimate the cost savings to be? We are alo flattening the entry to the family room instead of the arched opening.

Thanks!
