cool, must have taken a lot of work

Looks fun, I'ma try it

Really nice to see someone doing something like this! Nice job :)

Turbolifts are currently set up with a 2 block gap between for 6 block floors. If you change this then you need to change the code in the command block.

Command blocks can be used to create some fancy elevators through the teleport command. You can have a standard elevator that simply lifts you up one floor. You can add a block that sends you up multipe floors (say 5 to 10 floors at a time for a large structrure). You can also do elevators that go horizontal (side to side), diagonal or offset if you're adding an elevator to a previously built structure that doesn't have room for a vertical elevator shaft.

You need to have cheats enabled and give yourself block 137 through the command line (by pressing the T button and typing "/give <player_name> 137" or "/give 137" if on Single Player. To make the elevator command block you place the block either to the rear or side of your elevator car with either a button or pressure plate used to activate it. Then you right click the command block to access the interface. In the command line you type "/tp @p ~0 ~5 (or whatever your floor height is) ~0". This will take you up on the y axis 5 blocks (or whichever number you put in). To drop down it's "/tp @p ~0 ~-5 ~0" which simply drops you 5 blocks. This is the simplist version which creates an up/down elevator. If you have access to World Edit or Voxel Sniper commands you can make one box and duplicate it for an entire elevator shaft of any height. Note: The ~ symbol is between the escape and tab buttons. It simply means that you are moved that many blocks from your current position on the x y z axis. The - in the second example allows for negative/downward motion.

For more complex elevators you'll need to build the elevator car and duplicate around your structure (or build if you can't copy it). Then you need to hit the F3 button to get the x, y, z coordinates for each elevator car. You then use this info in your command blocks. For instance if on the first floor your elevator car is at the front of your building/structure and you find it's center coordinates are x= 567 y= 64 z= 345 you would go to the second floor elevator car and input "/tp @p 567 64 345" into the command block that you've designated for the first floor. Note: You don't put in commas "," between the x y z numbers. Took me awhile to figure that one out.

My cousin is currently using this in a hospital he's building. The ground floor and above have elevator "cars" stacked on top of each other. They are rather large but he wanted room to have buttons/command blocks to access all 4 floors from each floor seperately. The command blocks for these cars are mostly set up with ~0 ~6 ~0 or ~0 ~-6 ~0 coordinate changes (his floors are 6 blocks high). The basement car is rather offset because he had redstone circuits under the area where the above floor elevators are located. Command blocks sending you to the basement car have the actual x y z coordinates of that car "/tp @p 409 66 70". Note: The @p command refers to the player that is closest to the command block when the block is activated so be careful where you put it. For instance if you are on a server and your elevator is near a side corridor/hall and someone is walking by the command block when you activate it they could be teleported instead of you.

To further complicate matters you can make sliding 2x2 doors to access the car. Or for a simple turbo lift for Star Trek style ships 2 command blocks could be installed to the back of a single block room. Sliding doors would be optional for this application.
