If you’re on a private server, please contact the server administrator or moderation team for assistance.
Currently, there are no rules against building around other players’ structures on official servers. During the Early Access period, we’ll be continuing to add to the available in-game tools and options for dealing with this kind of behavior through play. These options will take time to design and implement, however.
In the meantime, please be aware that building up to a road or other unbuildable area will prevent your structures from being blocked off completely by others.
