Basic Lobby is a small mod which allows you to place a customizable structure at the world spawn point. This mod is primarily intended for modpack makers, and can be customized using a datapack.
Instructions on how to change structure: https://github.com/x3rmination/basic_lobby/wiki
Note: in order to spawn at the desired location, it may be necessary to set the spawnRadius gamerule to zero. This must be done manually.
