Everything was easy to access and we had easily expandable storage.
Since we have decay in mines now and cupboards need only one hit to disappear it's no longer an option.
We need an ability to easily store our stuff. Peoples around create whole factories and the best solution for storage is building multiple stone mansions. It's just tedious to come in and out of them to look for the stuff you need.
I can agree that storing it in cbs placed in mines is anticlimactic.
So my proposition to fix the problem is the warehouse building. Simple but big building to store stuff, at most two floors and big cellar, optimally should come in pair with some warehouse specific container eg "Warehouse Shelf" (9x9 storage, buildable in warehouse only, unliftable, 1x1 hitbox, 4 hard metal and 16 boards to build).
I can't believe that the same heartlings that can create great kingdoms, and traverse seas don't know how to build one... We can build ports, port towns were usually filled with warehouses.
