New structure I made

I made myself a new structure that no one has ever made. This I would like to call..."The mansions of all doom" or put it for short "The hell mansion". I have set up 4 floors, and each floor has 4 rooms. The first floor is a basic layer, and this one has 5. 1 has a potion room,  1 has a storage room full of copper totems and chests, and 1 room has an easier path to set a cave. Then, there's 2 basements: 1 is for the Nether, and 1 is an enchantment room. The second layer is more stacked and has more stuffs to prepare. 1 has an arrow shooting range, 1 has a storage full of weapons and armor, and potions, 1 has a room full of tamed dogs with armor, and 1 has the enchantment armory room. Then, the 3rd layer full of trades, maps, repairs, and upgrades. 1 has a black smith room, 1 has the trading room, and 1 is full of cartography. The last layer is where you enter the end world, and earn your special outfit which is the elytra. 1 is an empty storage, 1 is a tower that takes you up so high where you can fly with your elytra, and the last room is "The end" world. There's an extra floor which is called the watch towers. The watch towers can help you see what's out in the distance to see what's there. This structure is extremely epic rare (chance to find is 3.78%.) Each layer will be full of mobs, and starts off easy, but gets harder the more you progress. After killing every mob, you finally earn yourself the mansion, and you can either destroy it, take it over as your base, or leave
