I'm building a big bunker with a small guard fortress. The bunker is divided in three floors, First floor Farm, second floor Processing and Storage and third floor Dorms. The farm has every type of thing that can be grown on minecraft except flowers. Processing includes crafting benches, furnaces, enchantment tables, anvils and brewing stations. Storage has a lot of chests and also a mine cart system from and to processing and the farm which allows chestcart travel between the storage and the other locations. The dorms are currently under construction. Near the entrance of the bunker is an escape route which leads to the other side of the mountain. Credits to Nessonc for the fortress
