Staffed by a fleet of Mister Handy robots, and led by the three color coded Supervisors by the name of White, Brown and Greene, Graygarden is a bountiful greenhouse for the Commonwealth.
戰前由愛德華·格雷博士建立。 Here the Sole Survivor can trade with Supervisor Greene, start the quest Troubled Waters by speaking to Supervisor White, while Supervisor Brown will reward the player character for returning crop samples from the wasteland, which will cause the Graygarden workers to begin cultivating those crops as well as their original crops.
Due west of the main facility are two buildings. The first is a small garage with assorted junk components and a toolbox. The western building, Graygarden homestead, is a two story house with an Expert locked basement containing a chemistry station, assorted glassware and a pulse mine. The kitchen has collapsed and is inaccessible from within the homestead.
To the east there is a crashed Vertibird on the upper level of the highway with some ammo boxes beneath the overpass. A bit further east, near the next highway support pylon, is a window washer style elevator that lifts to the upper level. Walk back towards Graygarden to find a suit of power armor.
- Although this settlement seems small, thanks to the pre-existing crops and large greenhouse consuming most of the "floorspace," one could always "build up" as both the lower and upper segments of the overpass fall under the envelope of the settlement's boundaries, allowing them to be built upon with relative ease. (Some vehicles cannot be scrapped, nor can the cement dividers be removed.) Also broken highway segments are regarded as "in the boundary," so by making stairs it is possible to build over the highway.
- Codsworth will show a preference to Graygarden, and likes it when the Sole Survivor completes quests there.
- If one starts building at the lowest point in the settlement, it is possible to construct a structure up to 14 stories tall, although it will be divided by the highway.
Graygarden appears only in Fallout 4.
