Prevod - Nemacki-Engleski - I don't speak

I have the strong feeling this comes from some sort of video/internet-based game. Obviously, "Steinmetz building" does not mean much, except probably for players of that game. Just for the info, "Steinmetz" means "mason". For the second part of the sentence, "Rohstofffelder" is also pretty hard to translate without proper context, so I tried to stick to a form of neutral translation. The idea is that, in that other area, you can build those fields more intensely than in other areas, the "level" number is unlocked above "10". The second "build" could be translated to "upgrade", given the game background.
