there are no restrictions so to what or where you should build provided ofcourse you have a plot to build on and the buildings will fit.

certain locations would be more suitable for specific craft related building given the proximity to the resource nodes.

many communities are fairly close to some resources and some have there own portal and bindstones. with a tarbash disk and binding in bristugo you could basicaly bring whatever you need to your plot. Although its nice to have a reesource close by that you use in some of your crafting.
