Guild Building Questions

Me and my friends have a small guild and most recently found a nice little valley to build all of our bases in.

The one issue? Sub-fiefs too close which limit the building. We were imagining a small town/city with our own sections but all connected.

As it stands we cannot connect our bases at all. It would be great for a nice courtyard in the middle of them that connected them all with pathways.

Is there any way to accomplish this? The only idea I have is one sub-fief right in the middle that you stake out to encompass the area and then we all build our own sections, but then who really has ownership/pays taxes (even if you set everything to guild access). We do share resources and are just about to get into the DD, but since we are all at different points in the game it would be nice to currently not mix materials unless someone asks for them.

We have all these dead zones that do not and cannot connect, so even though I can build in their bases and them in mine, we cannot get the vision we hoped for and now my base is severely limited in size, I can only stake out in one direction (other than up) making my base one long line of a base. lol
