This is a Warehouse full of almost every item that is available in creative mode. This took me about 4 months of building and filling. I hope anyone that downloads it, can find it useful. The warehouse is made of bedrock so that it can not be destroyed. It is also fully surrounded by bedrock so that when you add it to your word, it blocks all lava, water and caves. There are 15 floors of items. Each floor has 96 rooms. There are a total to 1440 rooms and almost all are filled. There are some spares for you to add items. Each room has 5 double crates. Each crate has 54 slots. Depending on the item, there are 1, 16 or 64 items per slot. If it is an item that only fills 1 or 16 items per slot, there are multiple rooms of each item. There is also floor 16 which is a portal to the Nether. In this room, there is water that keeps the zombie pigmen from getting out. There are Golems on every floor that will help protect the Warehouse. You can also hook a lead onto the Golems and take them wherever you need protection. There are many levels of Cobblestone that can be mined. There are about 100 levels of Gold, Diamond, Emerald and Redstone Bocks in the corners under the Beacons. All you have to do is dig. The best place to put the Warehouse is in a flat area, and put it as far down as you can so that only the entrance level is exposed. Putting it out in the water is good, because you can make it an island. I have added farms on the top of the warehouse now.
Enjoy.
