A few simple structure ideas

So, I know some goobers are screaming in your face about how they think simple structures, such as jungle pyramids, igloos, and other things are too lame. I think they are perfectly fine, and PLAYERS are supposed to be creating these mega-builds, not for them to be generated naturally. So here I have a few simple structure ideas just for you! 

1:Old watchtower. Spawns in sunflower plains with a solid 50% chance. A 5x5x6/5 cobblestone/mossy cobblestone medieval castle with 1x1x1 windows (Just air) 3 blocks up. And a 3x3x3 (With gap for staircase in the shape of an L) floor on the 5th block up. Then, put a spiral staircase up to the ceiling made out of smooth stone slabs. Then add a 1x1x2 doorway in the middle of the 1 side that the staircase isn't blocking. in the bottom middle, there is a chest with loot kind of like the dungeon chest. And it will have a 25% chance of a skeleton with a helmet (Random durability and enchantments). It will also have a 30% chance of a horse spawning on the outer 3 blocks.

2:Soul alter. Soul altars are a small structure found in soul sand valleys with a 20% chance of spawning. It will have a chest with nether brick stairs on each side. Then, soul soil in the corners. And THEN, warped fences 2 blocks up from the soul soil. Then connect all the upper fences in the sides and middle. Then under the middle fence, put a soul lantern.
