Okay, Fallout 4 has some really great items already in place to build a settlement, From junk walls, to concrete fences to metal bunkers. I would like to recreate something a bit more close to the real world (in at least one of my settlements). Back in 2014 a show debuted on television called 'Doomsday Preppers" and it showcased dozens of individuals that were making plans on how to survive an oncoming apocalypse or meltdown of civilisation. On several of the shows people were shown using cargo shipping containers to create bunkers below ground and using the same kind of containers to also build well, compounds, almost fortresses above ground.
We have shipping containers already in FO4, but there is just a little something missing. The containers need some doorways cut out and / or one end with doors able to be opened. Then it would be possible to connect the containers together to make living space inside them when they are connected.
Maybe this idea will interest some talented modder and they can come up with some shipping containers that can snap together and have doorways or an open side option so that containers can be strung together to make a wall, or a castle, or anything in between.
