I had a house mod a while back and want to find it again. It was right next to Caldera it was a pretty big house it had Mannequins to put your Armour on and had a huge fountain in the basemant with tons of jars labeled to what ingredients to put in. Any Idea what this mod is called?

There is the Abandoned flat that sounds somewhat like it. It is located near Vivec though. I use it and have for the last decade..LOL! I remember how excited I was the very first time i walked into the secret basemant and found those jars.

Sorry I cannot help you find the mod you want..I will leave the link here ( i think that is allowed) just in case you want to try it out.
