The Mansion is the primary setting of Mad Father, and plays a large role during the game's events. Aya was born and raised in this Mansion and spend most of her time (if not all the time) inside this Mansion.
The interior of the Mansion consist of many rooms. During the events of the curse, various monsters and subjects have come to life and invaded the building. The Mansion consists of two floors. And a large basement, in which Alfred Drevis performs his experiments on human subjects. The Mansion also appears to have a lot of dolls scattered across the whole building, due to the fact that Alfred Drevis transforms humans into realistic dolls.
The exterior is considered to be very large, and a backyard is also present.
