i want to build a spawn city floati...

i want to build a spawn city floating island for my minecraft server. the server is called acid gaming and referring to the drug, acid/LSD. incorporate these components and then make ONLY 3 triangular pyramid structures centered around the spawn. these pyramid structures should have rooms with designs in them. also include 3 different psychedelic themed structure types around the spawn island that give players something to climb on or hide in, or just add more details to the spawn island. each design should be around the floating island and there should be many of each of the 3 structure types
