Brewery. This was a survival house/shelter where I spent most of my time at. chests contain stuff so do not mind it or simply trash all the collected junk.
lower level contains a secret lever near barrels to the brewing stash room.

Brewery was created mainly because of a brewing mod, that's why the barrels are in shape they are. chests in secret room were filed with alcoholic drinks that made an effect on player after overdrinking. a small portion on lower level was cutoff but it wasnt anything important, only a couple of cauldrons placed on top of fires.

Enjoy, don't forget to vote and/or comment.
