Originally, my plan for the industrial district was just two structures: a foundry for ore processing and the mine entrance itself.
The foundry has a forge, loose storage as well as chests, and a small furnace array for smelting.
Despite my original plan, the district already had two side projects that form a natural boundary between the agricultural district and the industrial district: a nether portal watchtower and a fishing shack.
And even with those, I felt there was something missing. So, I repurposed a stonecutter’s workshop from a previous world and built it across the road from the foundry.
I also added some natural decoration, with a grass path to the docks, and a small pond near the mine entrance.
Finally, my mineshaft has a simple design for now, though I do plan to improve it over time. I love building nice mineshafts.
