I may be missing something but I haven’t found anything like this.
I think the game would really benefit from storage that the spouse/family couldn’t access. I like keeping a clean inventory but if I put things in the larder, there’s a chance my spouse might use it.
I’m currently using a general store that I bought just to store things in…I never open it 😅
There are currently decorative chests so maybe it could be added to those?
