I'm building a town in my residence. It has small stores with cheap items. Houses and the hotel will be added shortly.
I don't want to sound like a "deby downer," but is 60x60 big enough for a town. In the wilderness you might have more room. Never the less, mabye I can help.
have a look around you have 60x60x128 from bedrock to the sky there are plenty of large builds you should have no problems with 60x60
