Built this for Computer_LP_Player owner of Lava City, and is made of clean stone and stone brick for the platforms.
It's up to Computer if he wants it to be accessible to reach the top.
Also good idea is to place fences around the platforms for details and other details.
Also I learned you can't use someones /home without them online so a couple times I fell and died then had to run back from spawn to there which is over 5000 blocks away across 2 1/2 oceans and a dense forest biome.
