It is a small two-level home. The second floor contains some ammunition boxes, metal boxes, and other random loot. It is set up much like a typical Megaton two-level building, with the main room being two stories high due to a balcony.
The Repair Bobblehead is on the table to the left of the door.
Evan King does not have a key to his house, so gaining entrance is impossible if the player character's Lockpick skill is under 50.
Evan King's house appears only in Fallout 3.
