The front door to the store is locked. Circling around to the back of a nearby house, there is a staircase that leads down to an open door to the basement. Stepping inside, there is a locked safe (Picklock 0) directly across from the entrance. Various loot can be found throughout this room, although the most notable feature is a deceased settler sitting in a chair with a pickaxe lodged in her chest.
A blasted out wall provides an entrance to a small cave system below the shop, which eventually leads to another supply room. An armor workbench can be found sitting against the northern wall here, with the stairs leading up to the backroom of the shop.
The second floor of the building is a living area with a kitchen and a bedroom. The bedroom holds Greg's terminal, as well as a red steamer trunk and a Vault-Tec bobblehead. A feral ghoul will crawl out from under the bed and attack.
Once unlocked, the southern door on the first floor will open to a number of old, heavy-duty vehicles near a shed with a weapons workbench inside. The shed is decorated with lights hanging across the ceiling, and just west of it is an exit overlooking the river. Turning right leads back out to the front of the store.

Greg's Mine Supply appears only in Fallout 76.
- Fallout 76 Vault Dweller's Survival Guide Atlas of Appalachia p.317, Greg's Mine Supply: "This hamlet is dominated by Greg's construction store, for all your mining needs! The store is locked up tight, but some enterprising individuals have burrowed under and across the road from the brick house, allowing access through a short tunnel. The supply shop has an upstairs area where you can secure Greg's Mine Supply Keys. Use them to open the door to the side yard."
