Special Containment Procedures: The [APARTMENT NAME] complex is to remain quarantined under the cover story that the building is an active public health hazard. All entrances to the complex are to be inspected weekly to ensure all barricades and locks are still in working order. If SCP-XXXX experiences a civilian intrusion, subjects will be detained and interrogated to identify potential links to GoIs, and amnesticized and released if no links can be found.
As of 10/05/2027, any further testing involving SCP-XXXX requires prior authorization from both the Ethics Committee and the Site Director. In the event that further testing is authorized, research teams must work off-site to prevent transfers of research materials from activating SCP-XXXX's anomalous effects.
If any D-Class apparel or standard Foundation medium-term exploration gear is found during any experimentation, all experiments are to be halted and Dr. [EXPUNGED] is to be contacted immediately.
Description: SCP-XXXX is the [APARTMENT NAME] complex, located in [REDACTED]. SCP-XXXX has selective reality-bending properties, where its structure and composition will become radically distorted to some observers while remaining unchanged to all others. According to experimental data (See Experiment Logs SCP-XXXX), SCP-XXXX’s reality bending effect specifically causes subjects entering the complex with the intent to deliver an object, idea, or service to a resident to be unable to find the residence they are attempting to deliver to. In other words, SCP-XXXX actively changes its layout to any deliverer so as to make their delivery impossible.
During testing, SCP-XXXX has demonstrated the following means to alter its configuration to an observer:
- Illogical/Non-sequential building layouts
- Misleading/Incomprehensible/Inconsistent signage
- Apartment numbers out of order/deliberately skipping numbers
- Extended hallways/staircases
- Fractional apartment numbers
- Escherian looping architecture
- Reality fractallisation and reduction
- [DATA EXPUNGED]
Despite the severity of some of these effects, all distortions appear to be localized entirely to the subject and have no effect on the baseline reality experienced by other residents of the complex.
While the pathway a subject may take towards their attempted destination may lead through extended segments of esoteric and non-euclidian architecture, it has been found in all nearly all cases that subjects choosing to abandon their delivery and leave the complex were able to do so relatively unimpeded.
Discovery: Foundation officials were alerted to the presence of a potential anomaly when automated scraper systems detected abnormal complaint rates from both residents of [APARTMENT NAME] and drivers for various delivery services, both annoyed with the inability of delivery services to complete assignments to the complex. Due to descriptions of potential anomalous phenomena being detected in some of the drivers' complaints (such as infinite hallways and maps changing between viewings), Foundation researchers were dispatched to conduct an initial investigation. After brief clandestine testing, Foundation researchers declared the site anomalous and initiated a takeover under “Black Mold” standard cover story.
Once the complex was vacated, further experimentation ensued to assist in understanding the constraints and parameters of the anomaly. Summarized logs of these experiments are included under Experiment Logs SCP-XXXX.
Experiment Logs SCP-XXXX:
Purpose: The goal of the experiment.
Procedure: The description of the experimental procedure, including personnel and equipment necessary.
Results: A detailed synopsis of the actual experiment.
Analysis: An assessment of the results of the experiment and resultant findings, as well as suggestions of future avenues of experimentation.
Purpose: To establish the presence/absence and severity of an anomaly at [APARTMENT NAME]
Note: This experiment was conducted after Foundation discovery of the excessive complaints about deliveries to [APARTMENT NAME] to ascertain whether the site was anomalous and, if so, the potential severity of the anomaly.
Procedure: One Junior Researcher will attempt to deliver a parcel containing one red brick to Apartment 11111
Results: Junior Researcher [REDACTED] located a map of the complex and reported to find Apt 1111 clearly marked within Building 11 in the Northwest section of the complex. Upon arrival at the indicated location of Building 11, [REDACTED] realized that this building was instead labeled "Building 10" and contained apartments 1000-1048. After no map could be found nearby, Researcher [REDACTED] searched for some time before locating a building labeled "Building 11". Entering the closest entrance, Researcher [REDACTED] was met with a nondescript hallway with apartment entrances staggered between both sides. At first, [REDACTED] experienced no anomalous phenomena within the hall, but upon passing Apt 1105 they realized each apartment was set further apart than the one before it. After noting a ████m distance between apartments 1108 and 1109, Researcher [REDACTED] was instructed to exit the complex, which they were able to accomplish by following their original path. During the return, [REDACTED] noted the same irregular intervals between apartments. Upon arriving back at the map they had originally consulted, they saw the map now indicated with an arrow that Apt 1111 was somewhere out of range of the map.
Due to the events described above, Foundation researchers declared the site anomalous and began the process of acquiring the site under the cover story it was infested with a pervasive black mold that presented an immediate health hazard to all residents and could not be cleaned without total vacancy.
Analysis: This experiment gives us plenty of ground for further testing, in particular regarding the anomaly's effect on the surrounding residents during one of these manifestations. Interestingly, the anomaly seems to not have a preference for whether there actually is a "recipient" for the delivery. This could prove handy for some long term testing, if this place ends up warranting it.
Note: Due to the complex being under Foundation control, this experiment onwards used D-Class personnel as the "deliverer".
Purpose: To ascertain the effect of reality distortions experienced by a deliverer on surrounding individuals
Procedure: One D-Class personnel will attempt to deliver a parcel containing one red brick to Apartment 12342. Junior and Senior researchers will be stationed within all apartments in buildings 11 through 133 and attempt to visually monitor the D-Class personnel's progress through windows, peepholes, and direct observation, as necessary.
Results: The D-Class consults the main map at the front of the complex and informs researchers that Apartment 1234 is not located on the map. After consulting visual feed from the D-Class' body camera, researchers confirm that no apartment within the range of 1200-1299 exists anywhere on the map. However, a label in the upper edge of the map indicates a "Building 12" somewhere outside the range of the map. The D-Class advances towards this indicated area, and researchers in Buildings 11 and 13 indicate being able to visually observe the D-Class at expected times according to his reported location.
Upon reaching the area indicated by the map label as "Building 12", the D-Class reports a large building with a similar external style to the other apartment buildings that extends virtually infinitely to both sides, despite official blueprints indicating Building 12 should be a similar size to the other buildings in the complex. Finding a doorway, the D-class enters and encounters a hallway, and signage indicates that the building contains apartments 1200-12███.
As the D-Class advances, Foundation researchers within the first range of apartments report witnessing them pass at regular intervals, as expected. However, after Apartment 1221, they encounter a junction with signage indicating apartments 1222-1234 in one direction and 1235-12███ in the other. After brief deliberation, researchers instructed the D-Class to continue towards the destination of 1234, and they complied. Researchers within apartments 1224 began to notice the D-Class taking longer to reach each of their rooms, culminating in a ███ minute delay between the D-Class passing apartments 1230 and 1231.
After more deliberation and consideration that previous experimental results indicated the D-Class was very likely still recoverable at this point, researchers decided to abort the attempt to deliver the parcel in order to avoid a possible ethics violation. They directed the D-Class to advance back towards the entrance of the complex and to advance down the alternate path towards 1235-12███. During this retreat, the researchers in apartments 1231-1222 noted similar delays between witnessing the D-Class as their initial progression down the hallway.
Upon passing 1222, the D-Class began following the alternate hallway towards 1235, and was instructed to advance until they passed Apartment 1268 and report their observations4. Researchers in each apartment from 1235-1268 noted typical delays between witnessing the D-Class passing by. Upon reaching Apartment 1268, the D-Class found the hallway kept extending indefinitely, with Apartments 1269 and onward being visible upon initial inspection. The researcher in Apartment 1268 was then instructed to open their door and relay their observations. Upon exiting their apartment, the researcher was able to see the D-Class in front of them in the hallway; However, no deviations from the original blueprints could be recorded from the researcher's perspective, including additional apartments from 1269 onward. Additionally, when the D-Class advanced further in the hallway, the researcher indicated the D-Class visually appeared to walk directly through the wall, and could no longer be heard. After this brief experimentation, the main research team decided to conclude this line of testing and instructed the D-Class to exit the complex, which they were able to accomplish without issue or deviation from their original path.
Analysis: There's a lot to unpack about how this site distorts space. This test seems to indicate that the site actually maintains as much parity with baseline reality as possible, as if the subject is still experiencing baseline reality alongside the anomalous distortions. The most interesting result is that the site seems able to manifest entirely new structures outside of euclidean space. While it doesn't seem like subjects are being teleported somewhere else, the anomaly is still somehow presenting them with entirely extradimensional spaces which don't seem to affect anyone else. Further testing is certainly needed on this.
Purpose: To ascertain what can satisfy the definition of "delivery" as it pertains to this anomaly, and ascertain the affects of the anomaly on multiple subjects.
Procedure: Two D-Class personnel will be given non-physical deliveries to Apartments 2222 and 3333, respectively. The first D-Class (D-4782) will be given information pertinent yet unknown to a researcher stationed in Apt 2222 and instructed to deliver this news to the researcher, while the second D-Class (D-8237) will be trained in basic plumbing maintenance and instructed to repair a toilet in Apt 3333, thus delivering a service to the apartment. If anomalous distortions manifest to both individuals, they are to meet after exploring their own anomalous effects to see the ways their effects correlate and differ.
Results: Note: For simplicity's sake, the events of both D-4782 and D-8237's attempted deliveries are relayed independently, despite both experiments occurring simultaneously.
D-4782 entered the complex first, finding Apartment 2222 indicated within Building 22 on the Northeast portion of the map. Advancing towards this location, they found multiple instances of fencing not indicated by the map. Upon arriving at the building, they found only one entrance, despite eight being clearly indicated on the blueprints for the complex. This entrance led into a small courtyard, with a set of stairs leading downwards into a metal door labeled "Building 22". Upon opening the doorway, D-4782 was greeted with more stairs leading down into a four-way intersection.
Within the intersection, D-4782 reported signage indicating the 3 pathways led to "2200-2210, 2211-2238, 2239—22165", and they were instructed to progress through the middle hallway. As with previous tests, as the subject approached 2222, they found the distance between apartments increase, but unlike previous tests, a right angle turn was encountered after apartment 2217. After passing this turn, D-4782 reported that the hallway then forked vertically, with nearby signage indicating "2218-2238 above, 2250-2217 below". After some deliberation, researchers decided to attempt the "above" pathway first, and D-4782 was able to climb into and begin exploring this segment of the structure.
Apartments 2218 through 2221 were encountered only a few meters apart as expected, but D-4782 reported that the apartment directly after 2221 was labeled 2223, with no indication of 2222 being anywhere nearby. Deciding to attempt the other path instead, D-4782 advanced back to the vertical fork in the structure and took the "below" path, again finding that apartment 2222 was omitted in sequence despite all other apartments on the signage existing where indicated. D-4782 then proceeded further down this path towards Apt 2217, after which they reported that they had inexplicably returned to the original four way intersection, entering through what would have been the "left" path on their initial entry into the building. The researcher stationed within Apt 2222 was instructed to step out and report their immediate surroundings. As in Experiment 2, the researcher reported no deviations from the original blueprints of [APARTMENT NAME]. Due to their proximity to the building's exit, as well as the experiment already yielding useful data, D-4782 was ordered to proceed back up the stairs in the intersection and wait at the outer entrance of the courtyard for D-8237.
Concurrently with D-4782's exploration, D-8237 had identified Apartment 3333 within Building 33 on the complex map, and began advancing towards its position. Upon reaching the indicated location, they reported that the building was indeed marked 33, but signage indicated that Apartment 3333 was not within. A brief survey indicated that the signage was indeed correct, and D-8237 was then advised to check within the nearby area for another map, finding one a few meters away. On this map, Apartment 3333 was indicated to be within Building 50, a further 310m North of D-8237's current location. D-8237 then advanced to this location, only to again find that the building's signage did not indicate an Apartment 3333 was within. They were then instructed to return to the map they had recently consulted to verify the location of Apartment 3333.
After making their way back to the map, D-8237 informed the research team that Apartment 3333 was now shown to be within Building 10, on the Eastern side of the complex, and was instructed to advance there to confirm if the anomalous misdirection occurred again. As expected, when they reached Building 10, no Apartment 3333 could be found. A nearby map indicated Apartment 3333 within Building 226, and researchers decided that they would proceed with the second phase of the experiment involving the two D-Class meeting for simultaneous observation of the site. D-8237 then advanced to the location indicated as Building 22, and reported that they also observed the building as a courtyard with a metal door recessed into the ground as the entrance, as well as observing D-4782 standing nearby.
At this point, researchers instructed both D-Class personnel to enter Building 22 again, keeping together until signage indicated that their delivery destinations were in separate directions. Upon descending the entrance stairwell, D-4782 reported that the intersection at the bottom was now merely a fork, and nearby signage indicated that the paths led to apartments 2222 and 3333 on one side, with the other path simply labeled "All others". Proceeding down the path with the desired delivery destinations, D-4782 and D-8237 both reported no apartments being present for a distance of ████m before arriving at another fork, this time with Apt 2222 and Apt 3333 on opposing sides of the fork. Researchers authorized the duo to split up and take the paths to their respective delivery destinations, , advising them to continue regularly reporting in after their split.
About 200m down their respective tunnels, both D-Class personnel reported seeing another person in the distance ahead. After being advised to take precaution but continue advancing, D-4782 realized they were actually seeing D-8237 walking towards them, and D-8237 soon after confirmed the same finding in reverse. The researchers then advised the duo to walk back towards their respective entrances again, and after a brief interval the D-Class met up again at the original fork. They were then advised to both attempt to navigate the path to Apt 2222 without splitting. After ████m with no discernible markings on the walls of the hallway, the researchers decided to end the experiment and recall D-4782 and D-8237. Despite walking a considerable distance, both D-Class found their way back and were able to exit the structure safely after some time. During the return trip, both D-Class were instructed to revisit a map consulted earlier by D-8237 and to identify any changes which occurred, including noted locations of Apts 2222 and 3333.
Upon checking the closest map, both D-4782 and D-8237 confirmed that, while the shapes of each apartment building seemed to match the known blueprints of [APARTMENT NAME], no apartment numbers were filled in, with a small legend in the corner indicating that Apts 2222 and 3333 would be labeled with question marks.
Analysis: I think we're starting to narrow down the parameters of this site. Beyond just establishing that the effect can manifest when an idea or a service is "delivered", we've established here that the reality distortions are independent of observer. Somewhere, somehow, these phenomena are physically happening, yet external observers will never be any the wiser. We have a couple of theories on how an anomaly could somehow manifest in this way, but even the most conservative involve fairly radical applications of currently understood anomalous activity.
This effect is certainly interesting to study, but I can't shake the feeling we're missing something major. There's obviously a pretty powerful anomalous effect at play here, considering we're seeing major non-Euclidean architectural distortions are possible that appear able to maintain stability between two subjects a considerable distance apart, but also mesh perfectly within consensus reality for everyone else. But the most unsettling thing is how tame it's been so far when we decide to pack up and leave. I mean, with anomalies like this, you never get to just pack up and go. They always exhibit some kind of unstable, chaotic behavior that makes retracing your steps damn near impossible. But this one seems almost deliberate, in that once you aren't trying to progress towards the delivery anymore, the effect doesn't seem to progress any further.
The main way forward seems obvious to me. Now that we seem to understand the parameters of what can trigger the anomaly and the extent to which it can affect baseline reality, further research should focus primarily on the extent to which the anomaly is capable of affecting the subject's reality.
We'll try the requisite robot experiment within the week, but sooner or later, we need to establish just how deep this anomaly will go.
Purpose: To establish whether SCP-XXXX's anomalous effects manifest when the "deliverer" is a non-organic subject.
Procedure: One standard Foundation remote quadruped will be deployed with a parcel containing one red brick in its cargo hold. The drone will then attempt to release the parcel at Apartment 1000.
Results: The quadruped was released without issue and immediately directed to a complex map for consultation and comparison to existing blueprints. After taking a few minutes to inspect the map, researchers determined that it exactly matched the blueprints as constructed obtained from the City of █████████, including the location of Apartment 1000 within Building 10 in the Eastern side of the complex.
Researchers then advanced the quadruped to the location indicated on the map, and discovered an apartment building similar to the others witnessed in the complex, labeled "Building 10", as expected. External signage indicated that Apt 1000 was within the structure, and after entering the building, the quadruped was soon able to locate Apt 1000 and deliver its package. The remote quadruped was then guided back out of the complex without issue.
Analysis: Well, well. After so many experimental questions answered affirmatively, it's refreshing to finally chuck something at the wall and have it not stick. The problem with anomalous testing repeatedly going right is that it never ends. If your anomaly can manifest on land, now you have to determine if it can manifest underwater. If it can manifest underwater, now you have to determine whether it can manifest while submerged in other liquids. Every time you prove what an anomaly can do, you then have to go one step further and define what it can't.
Now that we've established this anomaly can't be tested autonomously in any way, we can divert our focus towards the one parameter we've identified that can still be tested.
Next time, it won't be a quad making that delivery.

<START OF EXPERIMENT LOG>
NOTE: In accordance with Foundation Investigative Policy Sec 8.11.18 Order 47, the transcript of audiovisual data from Experiment SCP-XXXX-5 includes all portions that can be considered remotely relevant to the ongoing Ethics Committee investigation. However, for readability, extended sections of inactivity, such as [DCLASS5 NAME] sleeping or advancing through an extended hallway, have been omitted in this log. A complete transcript as well as the actual video records are available to any Level 4 and above personnel upon request, to be directed towards the Ethics Committee.
Day 1
The video starts with [DCLASS5 NAME]'s fingers still over the camera lens, the microphone buffeted with the noise of shuffling hands. After a few seconds the camera stabilizes and their voice can be heard.
D-XXXX: -fucker in place, now. Alright. Where are you wanting me to go again?
Dr. XXXX: There should be a map of the complex nearby. Go ahead and get the blueprints for the place out of your map pocket and compare them with that map.
D-XXXX: Got it. Let's see here…
D-XXXX spends 2-3 minutes comparing the two maps, eventually drawing attention to the Southern segment of the map. Analysis of the map from D-XXXX's camera feed shows drastic differences around Buildings 38-50, with the largest difference being Building 44 being indicated as a thin crescent shape on the Southernmost edge of the complex. Apartment 4444 is indicated as the center unit of Building 44.
D-XXXX: Am I good to start driving down that way?
Dr. XXXX: We shouldn't need any more documentation of that map. Proceed.
D-XXXX drives the ARTV South, and soon spots a large structure on the horizon.
D-XXXX: Uh, chief… Is this one supposed to be this big?
As D-XXXX advances closer, Building 44 begins to overshadow its nearby buildings, with at least 40 stories estimated from the clearest segments of video feed, in comparison to the 2 floors of the original building.
Dr. XXXX: We've seen a few different layouts. Just keep in mind, the outside really doesn't mean anything about what the inside will be like.
D-XXXX opens the nearest entrance to the building, and is immediately greeted with an interior resembling a luxury hotel foyer. The ceiling stretches up at least to the height implied by the exterior of the structure, while each floor wraps in a slowly descending spiral to ground level. The floor is decorated with elaborate geometric mosaics, and a small tile fountain can be seen gurgling on the far side.
D-XXXX: Are you still seeing me over there?
Dr. XXXX: Affirmative. Video and audio feeds uninterrupted.
D-XXXX: Well, hopefully that's good news. Where should I start looking around here?
Dr. XXXX: Do you see any signs anywhere nearby?
D-XXXX scans the immediate area. Over the entrance they just entered from is a placard that reads "0000". After a moment, they find a sign next to a hallway.
D-XXXX: Alright, the first one just says 100-999 is down this way. The other arrows all say 9999+, even though they point everywhere else.
Dr. XXXX: Can you advance down that hallway and try to establish contact with a researcher?
D-XXXX: May as well.
D-XXXX enters the hallway and quickly finds Apartment 0101. The Foundation researcher within reports seeing D-XXXX outside of their standard door, but does not see the elaborate foyer visible on D-XXXX's camera.
Dr. XXXX: Alright, well, not sure what we expected after our earlier tests, but it's good to know we still haven't pierced into baseline reality just yet. Let's try to find a way into that spiral.
D-XXXX scans the base of the foyer, eventually finding the point where the spiral connects to the floor. Beside this entranceway is a sign simply inscribed with "This Way" and an arrow pointing forwards.
D-XXXX: Well, the first apartment I see here is numbered 1000. And… Fuck me… This whole damn spiral goes up by ones.
Dr. XXXX: Just be thankful you've got the ARTV. Most poor bastards in your shoes would be footin' it on these expeditions.
D-XXXX: Well, still, shit's probably gonna take all day. This thing doesn't have an automate function on it, does it?
Dr. XXXX: It does, but that requires remote control. And we didn't rent the remote unit.
D-XXXX: Ah, well. Nice to know you care.
D-XXXX continues up the spiral for 18 hours, periodically conversing with Dr. XXXX and other members of the research team for basic entertainment and eating/drinking as needed. Throughout D-XXXX's time inside "Building 44", their GPS continuously broadcasts as if it were stationary at the edge of the structure as indicated on official blueprints.
Eventually, D-XXXX requests to rest, and the research team acquiesces.
Day 2
D-XXXX continues from where they left off the previous day, around Apartment 3027, and for approximately 4 hours continues uneventfully along the spiral, replacing the ARTV's battery for the first time at 2 hours along.
After this interval, D-XXXX reaches the end of the spiral, with the hallway forming the spiral fanning out into a number of different tunnels. No signage is in view.
D-XXXX: Are you seeing this? No labels on, what, 20 different doors? How the fuck is this supposed to work?
Dr. XXXX: Calm down, please. Since you've got the ARTV, we can follow any of these for some distance without investing too much time. Start with the leftmost path.
D-XXXX: Whatever you say.
D-XXXX begins advancing down the path, which begins with Apartment 3301 but continues in intervals of 0.5. The distance between apartments also slowly increases, as with other experiments. Upon reaching Apartment 3330, each half-interval apartment is a full 75m apart from the one before it.
D-XXXX: Still over a thousand out and I'm already getting this funhouse mirror shit? Can't catch a break.
Dr. XXXX: Well, you've got 19 other paths to try at that hub, if you'd like.
D-XXXX: May as well. There's no real sign this was the right way anyway.
D-XXXX advances back to the previous circular intersection. Although there are still a significant number of branching paths, the number according to later analysis does not exceed 15. D-XXXX emerges from the third path on the right and takes a moment to decide where to proceed.
Dr. XXXX:
