Spawn Tower

Here is my first published build, a spawn tower I built in my single player world.

I tried to make it an imposing, almost art-deco kind of building from the outside, that looks like a huge temple inside. I also filled the base with a 'mob arena'; a large room kept dark. Walk inside and the lights turn on -kill whatever mobs have spawned - then back out and they turn off again. On the sides of the arena is a few zombie/villager dispensers if you feel like watching them fight to the death.

The bulk of the base is taken up with a mob farm, but there is a large room left largely empty that anyone can customise (I build it before the villager trading update, and have since build a market in the free space). On each side is a simple dining room, bedroom(s), enchantment room, and storage/furnace room so you can comfortably live inside if you choose.

To get into the base there are two elevators, thanks to Cubehamster. I haven't tested them in multiplayer, but It should be easy to turn them into stairs if needed.
