That sounds like a great idea for a mod! A pack of wood and stone silos in a traditional European style would indeed complement old farmhouses beautifully. The price range of 30,000€ to 60,000€ is reasonable considering the capacity range of 175,000L to 350,000L. These silos would provide ample storage for various crops and materials, making them very versatile on the farm. They would also add a touch of authenticity and charm to the farming simulation experience. Overall, this mod concept seems promising and would likely be popular among players looking to enhance the visual appeal of their farms.
