Item #: SCP-083
Object Class: Euclid
Special Containment Procedures: SCP-083 is to be kept under constant video surveillance, with at least one Level 3 staff member on call at all times to respond to security breaches. Entrance to SCP-083 is permissible to Level 1 and 2 personnel with proper clearances, provided they wear a tracking device while inside.
Description: SCP-083 appears to be an uninhabited, two-story row house in a general state of disrepair, with an interior of approximately 366 square meters. It is located in the ██████████ block of ███████. The deed and property tax records for the address are missing after ██████. The last known persons to reside at the address were the ███████ family, but [DATA EXPUNGED]. Until acquisition by the Foundation, the property was the reputed "office" for local narcotics dealers who gained entry to the structure through a front window, since the locking mechanisms on both the front and back doors were corroded and frozen shut. SCP-083 first came to the Foundation's attention on ███████, when an altercation outside the building resulted in the front door being kicked in by [DATA EXPUNGED].
Those who entered through the door of SCP-083 (Group A) allegedly found themselves inside a fully-furnished and well-maintained home with functioning electricity and a fully-stocked kitchen whose appliances and decor appeared to be from the early 20th Century. Personnel who entered through the windows (Group B) described the interior as "dark and dilapidated," corresponding to the view through the windows. Personnel in Group A also reported that they couldn't see, hear, or find any members of Group B inside the house or of anyone else besides themselves. Group B observed that members of Group A seemed to "vanish into thin air" upon crossing the door's threshold.
Both groups inside the property not only described very different living conditions, but their descriptions didn't even correspond to the same floor plan. Their descriptions matched only in the relative position of the windows, since both groups saw the same street view. Personnel outside the house, however, reported only seeing members of Group B.
These observations were repeatedly tested and confirmed by staff, with the additional finding that the rear door of SCP-083 also leads to the "furnished" interior. Any non-conventional entry (i.e., windows, holes in the roof, down the chimney, etc), leads to the "dilapidated" interior, and persons inside the different interiors are unable to detect each other's presence, although they both register on standard spectral imaging equipment, so long as said equipment is outside SCP-083. It was also discovered that the furnished interior is not static. The floor plan of SCP-083 apparently changes, with a different layout and different numbers and kinds of rooms manifesting (see Document #083-A). No clear pattern or set interval has been observed in the rearrangement of the interior of SCP-083, but the phenomenon has never been directly observed or experienced by personnel while inside SCP-083 (see summary of experiment 083-03, listed as Document #083-C). So long as a human presence exists inside, the floor plan seems to remain stable. Although the "furnished" interior appears to be well-maintained, no inhabitants or custodians have ever been detected.
Addendum: It has been recommended that SCP-083 be evaluated as a possible autonomous object.
Document #083-A:
Nineteen walkthroughs of SCP-083 have been conducted to date ██████, and each has produced a unique floor plan with a combined total of 154 different rooms, with 17 of those rooms present on more than one walkthrough, though in differing locations (see Document #083-B). The rooms conform to a variety of decorative styles, representative of major artistic trends of the late 19th and 20th centuries, complete with era-appropriate furnishings and technology. However, each of the 19 floor plans still equaled 366 square meters of space, and in each walkthrough, the front door has so far consistently led directly to the same Victorian front parlor, designated FP-0. The rear door [DATA EXPUNGED].
