Tutorials/Door-based iron golem farming

An Iron Golem farm is an easy way to aquire many iron ingots (and less useful roses) with minimal effort after the initial setup

Design by JL2579
This design created by JL2579 is very efficient, with an iron golem appearing approximately every 1 1/2 minutes. This design makes use of four iron golem spawning locations, two stacked on top of each other, and leading to a central collection point. The video tutorial is by docm77.

Design by trunkz
This design created by trunkz has an average spawn rate of an iron golem every 6 minutes. This design is more resource friendly, however the spawn rate is less than JL2579's one.

Step zero - resources
To build an iron golem farm, you should have a fair ammount of resources, such as cobblestone and wood, as well as a way to get villagers into it.

You will need:
 * at least 1100 cobblestone (about 18 stacks)
 * 64 doors (6 wood per door=384 wood planks or about 6 stacks.)
 * 18 water buckets (or 20 seprate trips to a water source)
 * 1 lava bucket
 * 4 signs
 * 16 glass or fence

Step one - Building location
To build the Iron Golem farm you should:


 * Choose a good location. Don't build it far from your home or main base, because you want the golems to spawn even when you are not at the farm. An ideal spot is on top of your existing home.


 * Gather the resources listed above.


 * Follow the instructions below to begin building the base.

Step two - Building instructions

 * 1.

Start by building a 4x4 cobble base.


 * 2.

Continue this until you have a tower that is 10 blocks tall. Next, bust a 2x3 hole in it so the golems will be able to go through.
 * 3.

Build out 7 blocks from the top of this tower to form am 18x18 platform with a 2x2 hole in the middle.
 * 4.

Build in 4 blocks from each corner, then 3 blocks diagonal in both directions to build a triangle.


 * 5.

Next build a 1 block wide platform around this so the platform is now 20x20.


 * 6.

Now build a wall with windows in it as show below. This is how wide each of the holes in the wall should be:


 * 7.

Seal off the backs of the windows, and build some small cups to hold the villagers. The cups should be 4x4 on the outside, so there is 2x2x3 of air on the inside.


 * 8.

Place doors against the back of the indents. This is to make the villagers think these are homes. it should look like this:


 * 9.

Then place down 1 water in each of the 4 villager cups, and 2 water down in between each of the raised triangles to form this pattern:


 * 10.

Place 1 water on each of the triangles in the very back corner of the wall.

Now the top part is finished, the golems will spawn once there are 3 villagers in each of the holding cups. The next step is to build the golem grinder.


 * 11.

Build 4 blocks out from the bottom of the tower and 3 blocks up on each side, then place 2 blocks at the end of it to keep the golems from escaping.


 * 12.

Next, place 4 signs in a cup shape to hold the lava that kills the golems.


 * 13.

Now place the lava in the signs.


 * 14.

Place the last 2 water in the very back of the base, so the golems will get pushed into the lava.


 * 15.

Put down 2 hoppers going into a large chest for automatic resource collection (this is not required, but it is a good idea so you don't let any of the items despawn.)
