How much value does a vaulted ceiling add?

[Tasia Turner]

We are in the middle of a rehab and the contractor is removing part of the ceiling to add support beams and open up the kitchen. While looking at the space today, I realized half the ceiling is already ripped up, and it could be awesome to vault the ceiling. The added cost of labor and materials would be about $1,500. Anyone have experience with how much value a vaulted ceiling adds? I’m considering doing it, but I don’t want to over-improve. Thanks in advance.
