This mod is one of several settlement concept builds.  FOB Nordhagen is a sole survivor built Brotherhood of Steel forward operating base.  FOB Nordhagen's primary function is water purification, but also houses numerous power armor sets recovered from the Commonwealth that are being converted for Brotherhood use.

Sole Survivor's quarters are meant to be the room underneath the crafting station/weapons and armor workshop area.

Sharing this settlement would not be possible without Transfer Settlements: http://www.nexusmods.com/fallout4/mods/22442/?
Many thanks for the authors of Transfer Settlements, they've renewed my interest in settlement building in Fallout 4.

The blueprint also requires the following mods:
Homemaker - http://www.nexusmods.com/fallout4/mods/1478/?
Armor and Weapon Keywords Community Resource (AWKCR) - http://www.nexusmods.com/fallout4/mods/6091/?
QMan's Craftable Lanterns - http://www.nexusmods.com/fallout4/mods/7870/?
Fallout Themed Paintings - http://www.nexusmods.com/fallout4/mods/5283/?

Wasteland Workshop DLC
Contraptions Workshop DLC
Vault-Tec Workshop DLC

This settlement breaks the build limit, so you'l likely need a mod that increases build limit.
