The vibe I was going for with this settlement was mostly survival, improvised and makeshift. I didn't actually add that much to the settlement that wasn't there before, the main structures stayed pretty much the same I just changed their purposes and made them more sealed, barricaded ... something you would expect from a post apocalyptic sanctuary of a lone survivor scavanging and hunting for his survival. All the main assets are Vanilla and DLC ones. I also played around with OCDecorator to make it feel more immersive and lived in. If you wish to have more detailed version of this you need to download it. Unfortunately, you will have to download Homemaker if you haven't already for some reason some structures don't load properly without it even if I haven't used it in this build.
