The BuildersUnite network has multiple servers to keep anybody entertained.

The servers we currently have are:
-Creative
-Survival
-Skyblock
-And more to come!

Our creative server is freebuild (no plots) but we utilize multiple grief preventions to protect your builds. We have multiple worlds that everybody has access to, including flat, biomes, and a void world. We also have our own custom buildoff plugin for you and your friends to challenge each other to see who can build the best!
