The House on Arbor Hill

The House on Arbor Hill, also known as "The Psycho House" by some members of the neighborhood, is located at 1 Arbor Hill, Boon County, Oregon. It is the main residence of the Greenbriar family after Terrence Greenbriar inherited the property from his uncle, Oscar Masan, after the latter's passing. . The Greenbriars – Sam, Janice, and Terrence – moved into the estate during the summer of 1994.

History
The house was built prior to Oscar Masan's birth, and it became the home in which he grew up and eventually spent the rest of his life. In the 1950s and 1960s, it often hosted Oscar's sister and her son, Terrence, particularly during the holidays; however, some time after 1967, Terrence ceased visiting his uncle, and did not return to the house until 1994 when his family moved into the property.

Description
The house totals three stories in height including an attic, as well as having a basement used primarily for storage. There are interior doors to every room, including doors that restrict access to the east and western hallways on the ground floor. There is also an upstairs and a downstairs bathroom, and an ensuite in the master bedroom. After the Greenbriars moved in, the attic was renovated into a darkroom for Sam to develop her photography.

Additionally, there are a number of secret passages and nooks. These were discovered, and subsequently exploited, by Sam and Lonnie during their various explorations of the house.

Ground floor
The ground floor is the first area Katie enters upon her return. While the eastern hallway is initially locked, she is able to wander down the western hallway, or go upstairs to the second floor.

Second floor
The second floor of the house contains the bedrooms for the Greenbriars, as well as access to the attic. Sam's room is directly down the hallway, with the master room and its en suite across from hers. There is also a guest room, which has Katie's things in boxes, a sitting room, and a sewing room.

Basement
The Greenbriars primarily use the basement as storage, though there is also a boiler located just down the stairway near the library. This is also where the now-defunct servants quarters are, with a functional bathroom and old-fashioned bell system.

Attic
The attic is accessed through a panel in the ceiling on the second floor. Sam had converted it into a dark room for her photography, and strung up red lights around the entrance to warn off her parents. In addition, the panel was able to be locked. While the attic is not very big, there is enough room for some furniture, including a small futon in one corner and a table with a couple of armchairs.
