Simple, Defensive Fort/ Server Spawn

A simple fort I threw together, has 4 entrance/ exits w/ retractable lava traps.
Interior of the fort is currently empty, If desired I will fill it in, but it has been left empty so you all can customize it as you want.
I will upload a second version in a day or so with the interior filled in as I want it, complete with:
- Horse corral, and Sheep, Cow and Pig pens
- Semi Automated: Wheat, Carrot, Potato, Watermelon, Sugar Cane and Cocoa Bean farms
- 4 Player area's with Storage

FOR COMPLETED SECOND VERSION PLEASE SEE: HERE

Additional Notes

The texture pack used is the light version of Conquest, Google it.

Please feel free to leave me some advice and criticism of your own.

Let me know if there are any issues with the schematic, or any of the devices!!!!
