Wilks' house in Grayditch is a main location in the quest Those!, being found next to Doctor Lesko's recently built shack and across the street from the Brandice's house.
The house is a two story building, with a living room, kitchen and bathroom on the ground level. In the kitchen, there is a fridge. In the restroom, a first-aid box is mounted on the wall right beside the opening. Upstairs, there is only a bedroom containing a queen-sized bed.
Before the quest is completed, it contains three or four fire ants corpses and Fred Wilks' dead body. The house is left in a bad state of rubble and flames, left from the fire ants. Fred may have fought them to the death, killing a few before being done in himself. When Those! is completed and you choose to help Bryan Wilks find a home, he will clean up the rubble, bury his father, and remove the fire ant corpses.
- When fast traveling to Grayditch, you will spawn across the street from the house.
Wilks' house appears only in Fallout 3.
