Lucy West's house is located east of Megaton's plaza, above Mister Burke's house, in the settlement of Megaton. It is the residence of Lucy West, who can give you the quest Blood Ties.
The house is a two-story structure. On the ground floor, there is an alcove for the storage of items and a small living and dining area where a table with two chairs have been placed in a corner. Stairs lead to an upstairs sleeping area equipped with two beds. Additional furniture includes a filing cabinet and a locker.
Lucy West's house appears only in Fallout 3.
