My Lands: Black Gem Hunting

I founded a new city on a set of empty land, only to learn that the outer ring was filled with alchemist labs, which appear to be owned by another player, and i have no ability to interact, demolish, etc them whatsoever even after i upgraded the dark citadel as far as it could go. Is this a glitch? is there a building im overlooking? how do i get rid of them so i can build my own or is there a way to just flat out claim them and use them?

The wiki explains how villages work.

The only way to build in this village is to attack the other player and destroy his buildings. But I wouldn't try it if I were you. The player in question seems to be much stronger than you. In my opinion, the best course of action is to destroy your city and build another one in a more suitable place.

the link helped, wasnt aware that could happen or i wouldnt have built where i did. And yes, that person seems much, much stronger then i am =p relocation eminent.
