90’s era NG fireplace with tile and drywall surround. I want to build a whitewashed stone surround and replace the mantle with a chunky piece of reclaimed lumber (or even a reclaimed mantle) for a more cottage-type vibe. My questions are:

1. Do I need to rip the tile and drywall out and redo it for a flat base?
2. Or can I build out the stone directly on top of the drywall as is?

I have experience with most home maintenance areas and also some drywall experience. I also repaired this fireplace when we first bought our home, but I really don’t know shit about fireplaces or stone work.
