So,I found a nice village in my survival world (which I copied and decided to survey in creative mode) and I want to build some sort of huge castle or perhaps an organized settlement with paved roads,houses,an underground rail network and the like. Originally I was thinking of something along the lines of the Twins from GoT functioning as the main two forts leading up to the village and making the rest of it a normal settlement. Another idea is doing the classic huge,blocky,4-wall monstrosity surrounding the settlement. However,I'm still not sure on what to decide,so,if any of you want to,go ahead and at least draw up a rough sketch of any ideas you have on your mind. Now,I'm not asking anyone to spend hours thinking this over,but rather I just need a simple rough outline of any ideas you might have,so that I can finally start working on this.
