I began to look at Mills and housing that are found in these different environments. This inspired the interiors of my level. I felt that with the mill in particular there was a lot that could be done with a combat-focussed game. The feudal, "poor" feeling of these buidlings was also what made me resolve to add a fortifed manor house, suitable for a lord or baron. I situated this on the highest ground, with the village below it within the natural defenses of both the hills and the bends in the river.
This is how fortified manor houses were built up in history.
