That Iron farm (max size) takes 45x45 according to the video.

If you build it directly over the spawn it would roughtly look like this:

Spoiler Alert, click show to read: 

(from spawn 0,65,0 -> right top corner: 22,65,-23 -> right bottom corner: 22,65,22 -> left bottom: -23,65,22 -> left top -23,65,-23)

Maybe current spawn location doesn't cut it. Would it help to move the spawn? or does it have to sit atop the 0,65,0 coordinate? It says spawn chunck no spawn point. Is there a difference?
edit: Ok, read up on it. Apparently the spawn chunk are 12 by 12 chunks around the spawn point (192x192 blocks) and can't be moved.
