Sanctuary Hills Overhaul
If the Abernathy Farm Overhaul piques your interest, you'll want to take a look at this mod from the same author.
Sanctuary Hills Overhaul is a beautiful take on the first settlement you encounter once your character leaves the vault and enters the wasteland.
The mod, which is available for both PS4 and Xbox One, comes with a complete wall that surrounds the settlement. It comes with a main gate and a back exit. Guard towers to protect the settlement from outsiders. Free space to build your own structures. And the highlight, a tree house in the middle of the settlement.
The tree house comes with a power lift that will take you and your companion to an extremely nice perch.
This is a perfect mod for those that don't like building new settlements but like to decorate. And it's an excellent choice for those going through a second or third play through.
