The series concerns a "house at the end of the universe," as one character terms it, a dwelling of mysteries, mind-states and inner-space. Here are a few views of the home in question. The series was shot in stark black-and-white, and hence these photos are in black and white too.
Left: The main hall. In episode #4, "Visited," this staircase turns into a battlefield between those trapped inside the house, and a force from outside that wants to get in.
Left: The upstairs hallway. This tight space is the location where Astrid first meets Bill, the house's "man of science," also trapped there.
Left: This is Astrid's room. In episode # 1, "Arrived," Astrid (Kim Breeding) awakens in this room...naked. She finds all her clothes hanging neatly in the closet....
Left: The foyer downstairs. Throughout the series, all the windows are "blacked out" because of a strange "null space" surrounding the house.
