Every building could claim a box of land and higher level building could claim more of it.
Upon territorial collision with other players' building the shape of borders can change (to polygonal) and other building's can't claim other players' territory. So first placed get the whole terrotiry.
The first village placed by every player get's the "Capital" upgrade, which means it claims land in a much wider range (like 10x10). The reason for that is players only can build in their own territory.
