This is my survival home on the Wired Minecraft server -- it was done completely in survival mode -- however, I did use fly mode after sacrificing 32 diamonds.  It includes pretty much everything you need (all the automatic farms except wheat, auto-potion making, etc.), and took about 2 weeks to build and much longer to get all the stone and harvest all the wool for the wizard statue.

I did the rollercoaster afterwards, and that took about 9 hours and a lot more material gathering.

Any suggestions on what to add to it?
