I made perimeter for my base around back in the beta, and transported into another world by MCedit when new updates are came out. I build a lot of things since beta. Hope you get something out of my posts.
Overview of my parameter:
New image incoming
This area is pretty empty might want a idea about the build.
Anyways, back on topic.
I think a nice, BIG castle would do it.
I had idea about that at the top left side of the parameter looking for some designs. Idea was build castle by follow the geography of the mountain. It looks more natural. Also, there is library underneath mountain.
Anyway, thank you for the idea.
What I like to make is fill everything with leaves and vines to give buildings a post-apocalyptic fell. Don't know if you like this style of building, but at least it's a idea. Anyway, good luck improving your already awesome base.
