I am planning to have larger factories in the city, specifically north-west of the tower bridge. We need power plants, refineries, production facilities, warehouses etc.
If you want to build something like that, please inform me. I do not have a limit on the size. I can reserve a space in the city for it, mark it out and you can build directly there with your friends. I will give out rewards for quality finished projects to those who helped with it.
