Minecraft wiki entry for Elevators, associated text: Besides from the minecart elevator, command block elevators can be made with some special effects, and are the quickest of all the elevators. The principle is that you can hit a button wired up to a command block with the /teleport @p <x> <y> <z> command. (Alternatively, you can replace @p with your username, creating a player-specific elevator.) The most basic design is to have the command block behind the button. To get a little more complex, you need a bit more room or use repeaters. The basic objective is to have a command block with the /tell @p Going to [floor name] command, then a few moments later, having a command block with the previously mentioned /teleport command to do the main part of going to a floor. Note that if you are using this with a high-rise building, you may need to create more than one elevator cab for serving more than a few floors, since this type of elevator may get a little large, trying to serve 35 floors in one cab.
