Empty Sky Island

I needed a base to begin building a server hub, so I created this. This build is a half-sphere with a radius of 30 blocks to build on. The top layer is grass and the lower layers are made of stone. The center block is marked with bedrock. When spawning in, the build will spawn with you in the center, top layer.

To place this in your world, I recommend using World Edit.

Hope this helps!
