This is the server that I normally use for building. I use this over Bob the Builder, because it also gives you the option of using explosives to test out your new base. Rockets and C4 are banned on Bob the builder.


You can also use this server to train you AK spray, try various weapons, arena with your friends, etc.

You get unlimited materials, no clip, crosshair, you can spawn in whatever items you want.

It also offers protection from griefing. Other players can't mess with what you build.
