Oberland SkyStation is a Minute Man settlement designed around the concept that if the bad things can't get to you, they can't hurt you.  Or the designer didn't get to spend enough time in tree-houses as a kid.  Because tree-houses are cool.

Current version comes without interior decor beyond beds, that will be added in a later version.

The area on top of the stacked blue box cars is intended for a player house once I settle on a design I like.

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/?
Wooden Prefabs Extended - http://www.nexusmods.com/fallout4/mods/10140/?
Wasteland Workshop DLC
Contraptions Workshop DLC
This settlement breaks the build limit, so you'l likely need a mod that increases build limit.
