Ya see, i built an i-ron farm with two spawning levels. It works aight except that fairly frequently I have a Gol'm spawn outside of the spawning area (that there water).
I think your spawning room is not big enough. The design I have used uses a 20x20 block room (18x18 intenral). I believe Iron Golems will spawn in a 16x16 block area around the geometric barycenter of the "Village".
As your design appears to be about 10x10, they might spawn outside your spawning room.
Edit: You might also have issues with them spawning below your spawn pad, as the spawn area is 16x16x6, and your spawn floor looks to be about level with your doors, Typically, you put in two spawning floors, to maximise the available spawn locations.
Easiest fix would probably be to change your central drop shaft to a 3x3 or 4x4 rather than 2x3 shaft, then expand the rest of it by one or two blocks to keep the water flowing right to the edge of the drop shaft. Yeah, you'll have to put signs on signs, which is a bit cheaty, but you could probably do a piston-based system inside to push them into a deeper, narrower, central 2x2 shaft within the main 4x4 shaft.
Or double check that there aren't any other wooden doors with nearby sky exposure counting as houses, pulling the barycenter slightly off your central shaft?

You need to remove all spawnable blocks except those you want the golems to spawn on. I tried having my villagers in mine carts in a pocket around the outside of my farm, but golems were spawning on the dirt blocks I had the tracks on, even though there were glass blocks two above them. I had to replace the dirt with glass -I left the villagers in their minecarts, and just push them around- and it works perfectly now.
This is the tutorial I used to build my farm, except I didn't bother with the sorting system, and as I mentioned, my villager pocket goes all the way around (not full though, maybe 20 villagers) and they're in mine carts (so much easier to control them that way). As long as the only blocks that are spawnable are within the farm and under the water, it works perfectly.
Yep, removing all spawnable blocks other than the ones in your water stream will also work. Leaving the spawn area smaller than 16x16 could decrease efficiency though, as the game will select a random location within the 16x16x6 area and test if it can spawn an iron golem there. So the less valid spawn locations you have, the more likely that test will fail.
That probably wouldn't have a huge impact on efficiency though, not sure.
One thing you could do to improve efficiency without increasing the size would be to use ice (preferably packed ice) for the spawn floors. That way any spawned golems will move pretty quickly off to the lava blade, increasing the frequency that iron golems can be spawned at.
Yes, I built one of these farms (MCTUT) , and it says in the tutorial you can have no spawnable blocks around the outer edges, and you have cobblestone around the area outside the doors. Even the top where you've removed a glass block and stuck a torch will allow a golem to spawn I think, should use glowstone as per MCTUT design.
As another post said, the design is fairly simple but also fairly inefficient. I expanded my design to 18 x 18 pads to maximise the spawn area, this does require a bit more design, as in you'll need water source blocks along each edge (except each corner 2x2 area which should be blocked) and villager pods on opposite sides.
Gumbatron, I'm certain mobs don't move faster on packed ice when in water streams...
Hmm, ok. I might be wrong about that, thought they did though, will have to test it out some time. Sorry for misleading people if I was incorrect :-)
Edit: I think I gained that impression from watching someone make a mob trap that used water streams to flush the mobs off the platforms. They used ice for the platforms so the mobs would be swept off faster (at least that was why I thought they used ice). Perhaps they were also mistaken :-), Will test it out when I can and report back
Further edit: Haven't tested it out myself yet, but I did find this snippet from one of the Minecraft wiki's (not the official one though).
From http://minecraft.wikia.com/wiki/Ice -
"In Mob traps, Ice is great for making faster Mob delivery systems. Water traveling over Ice propels items and Mobs faster, decreasing the amount of time the Player must wait"
Ice and packed ice DOES make both items and mobs move faster....just not by a whole lot in the case of mobs. Items move much, much faster on ice or packed ice in a water stream, but mobs, especially mobs trying to go the other way, only go like 20% faster as measured by admittedly imprecise tests a couple of players made on our server.

That was what I though. Although, last night, I set up a rudimentary test to see if there was a noticeable difference, but found none. My setup was just a 16 block long tunnel (2 blocks high, with a roof). Two tunnels side by side were fed mobs spawned from a dispenser. It was basically a photo finish at the end. So, really, I dunno. It would make sense to me that mobs would move faster, at least when they aren't jumping, over ice. Maybe there are some different scenarios that I haven't tested, such as when the mob is actively trying to move with or against the current.
Gives me an idea to go and find some cats and install them in my skele spawner, that might hurry them out of it a bit?
Sorry to resurect this old thread but I assume with updates it can be helpful. Nice video Shyraven1.
i have done 4 days of 6 hour AFK experiments on my iron farm and I'm having two issues with ps4 game play.
villagers glitch out the glass sides once I start the game. I haven't seen them glitch out the front of the 6 long glass pouch only out the sides. I think I have corrected this with water source blocks on the opposing ends to keep villagers off the sides.
Iron gollums would spawn on glass blocks with solid blocks under them outside the intended spawn area. I removed all non glass blocks and a short test was successful.
if either the villagers glitch out again or the gollum spawns outside the intended area I'll edit tomorrow.
Iron gollums would spawn on glass blocks with solid blocks under them outside the intended spawn area. I removed all non glass blocks and a short test was successful.
Just a minor point of pedantry, I think the golems were actually spawning in the glass, the same as they do in water, and then stepping up out of the glass. I've actually seen them do just that, except in my case it was slabs, not glass, but both count as transparent blocks.
About the villagers glitching out of the pouches, were the corners filled in?
Like so:
Rather than:
....
I had an automatic chicken farm once and the chickens glitched out the corners untuil I filled them in.
When I first researched building an iron farm, I noticed the overall issue with them is villagers glitching outside their holding pens. This is sooo easy to remedy: keep the villagers in individual cells (and in a minecart). They won't be moving on chunk load/unload, thus have no chance of glitching into a solid and suffocating or into a transparent and escaping. In 2 years, I have yet to lose a villager stored in such a manner (in an iron farm, villager mall, etc).
Villagers in minecarts CAN move, even without rails under them. And villagers in minecarts ride right into solid blocks and suffocate even easier than getting pushed in there. There seems to be no one perfect way to store villagers that is immune to all glitches and bugs. Nor does there seem to be a good way to store them which is immune to zombie spawning in either village sieges or their phone-a-friend ability. I've had zombies spawning on glass or on wool-over-water in my individual villager storage chambers. Hopefully all the bugs they're squishing with the 1.9 snapshots, and/or the tweaked entity collision rules, will solve some of these problems and we'll have a non-annoying villager storage method at last. Although the spawning-rule tweaks sound like they'll make the zombie-spawning problem even worse.

Farm is now working properly. Yes I have the corners filled in. Not sure if I did to begin with since I tweaked it about 5 times now but the end result is corners filled, water flow on opposing sides of pouch. All glass blocks used.
I I think I tried to remedy the villager glitch with solid blocks and water which created the gollum problem. I should have tried one remedy at a time as a process of elimination rather than trying water and solid blocks. But thanks all.

Interesting, Martin. Yes, they can be moved, but I don't think they can move on their own... I've never seen them move without another mob/player getting closer than 1 full block; with their cart in the middle of 8 blocks, and no rail beneath, I've never had a problem, since once their enclosure is complete, there shouldn't be any outside force. Say what you will, but unless you can provide steps to reliably replicate the behavior you describe, I'm going to have to say 'huh-uh'. Perhaps in older versions or new snapshots are different? I refer only to 1.8.
The only mob I've seen able to move itself in a minecart without rail below is a baby zombie chicken jockey (and they're fun to watch too!).

Sometime back in 1.7, a friend was trying to get an iron grinder and trading mall set up in The End, and she had a lot of problems with the villagers moving in their carts on a flat endstone surface. She ended up putting them in 1x1x1 holes in the carts, and that stopped the movement, but she lost a couple over the edge of the hole she was using to dispose of ones with unsatisfactory prices on their trades. So it might have been patched out since then, haven't had any problems with that aspect lately myself. But then I haven't been trying to keep villagers in carts on a big flat empty surface, either, I have my own villager-handling system of rails to holding cells, but don't use the carts except on the rails themselves.

My village's size is (with included outer walls) 36x36. Spawning room for iron golems is 18x18 (20x20 with walls - look at the images one from ms excel and another from the game.
Iron golem can spawn everywhere in my village. Should i really place slabs outside of iron golem zone to prevent them to spawn? If you say "yes" then let me know how how many solid blocks iron golem needs to spawn. 2x2?
Thanks.
The golem spawn area is 16x16x6 in the center of the village. As long as your doors/houses are placed symmetrically around the trap area (so that the center of the trap is the center of the village) the golems will only spawn in the trap. Also note that slabs (or other transparent blocks) will not prevent golem spawning. Iron golems can spawn inside transparent blocks, including stuff like slabs and stairs.
Two things concern me from your pictures.
1. I don't see any doors -- where are the doors?
2. If your villagers are free to wander about they may (and very likely will ) all end up on one side or in a corner, and that could put the furthest doors out of range, causing them to be dropped from the village, which would shift the village center and the golem spawn area outside of the trap. To prevent that in my underground iron farm I trapped one villager in each corner to keep all the doors valid.
Eventually I moved the villagers with the best trades into the corners, so now my underground iron farm is also a small villager trading hall.
And one other warning: If your farm is larger than 28x28 it will large enough to support a zombie siege, which could mess up your villagers and possibly your doors..

As your design appears to be about 10x10, they might spawn outside your spawning room.
