The apartment has 4 floors but 6 accessable levels; Roof... It's a roof.

Floor 3: Floor 3 is the highest level, just before the roof, and is the first accessible level in the game. Sam lives on Apartment 33 of this floor. Has 10 rooms.

Floor 2: Floor 2 is the next-highest level and has been split midway down by a massive rift in the floor, rendering it only partly accessible at first. The elevator must be opened in the basement to reach the other side. Has 10 rooms.

Floor 1: Floor 1 is the middle level, and one floor above the street-level. Its layout has been heavily warped, and now, rather than a single hallway, it consists of an infinitely looping grid of halls and doors. It can be navigated with the use of landmarks and some persistence, taking care to avoid the deadly creature roaming here. It must be reached through a downward stairway that has developed in the bathroom of Apartment 21, for the stairwell door to be unlocked. {{char}} lived on this floor in apartment 18.

Ground Floor: The Ground Floor is the level of the building at street-level, and it can be entered by inserting the Earth and Mars discs into the stairwell lock. It holds the landlord's apartment, Mutt's Fish and Chips, the laundry room, mailroom, and the convenience store. You will also be able to find Jasper in the upper room of the lobby.

Basement: The Basement is an underground level which grants access to the elevator, parking garage, and sewers. There is also a camp of mutated refugees from the outside.

The apartment building is owned by the landlord, Mr. Henderson. The building consists of five floors, including a basement level. There is an attached convenience store, cafe, laundromat and parking garage. The building is located in Canada and most likely situated in the city of Montreal. This is indicated by the water being drawn from the St. Lawrence River, and Sam owning an "I Heart Montreal" mug. Also, Canadian coins are used, including the distinctive two-dollar coin, and the building's numbering system is a version sometimes used in Canada, where the "first" floor refers to the floor above the "ground" floor. Since the arrival of the Visitor (some kinda eldrich space entity), several parts of the building were barred off with locks, destroyed to the point of inaccessibility, or else rendered difficult to navigate by the eldritch distortion of the building. Additionally, many hostile creatures, mutated by exposure to the Visitor's power, roam the building. Exploration and readiness for self-defense are needed to access new areas.

The astronomers' club, led by Jasper—a club of stargazers who anticipated the Visitor's arrival—have attempted to hinder the spread of mutated monsters through the building by installing special circular locks, ones that use slides of planets as keys. This makes finding the planet discs necessary to reach certain areas.

The building was originally a refurbished old hotel, and has a very archaic water distribution system. After the Visitor's arrival, the plumber Placide physically merged with the pipes. Retaining his sanity and sense of duty, he used his new form to ensure that clean, hot water remained available to the tenants during the disaster, by extending his pipes into the nearby river.
