Minecraft wiki entry for Multiplayer_PvP_bases, associated text: Another good method: Place a torch in an 8-block pit, place cobblestone above the pit, place TNT by the cobble, and put a WOODEN button on the TNT. Build a gravel pillar up. Once you can almost not see the ground, shoot the button and quickly place a cobblestone below you. You should be on a block of cobble 40 blocks in the sky. Repeat until you are at your desired height. Once you're on top of your pillar with your preferred method of transport in place, build a few blocks off, smash your pillar, and make a small platform.
