Item #: SCP-8634
Object Class: Safe
Special Containment Procedures: Due to its nature, SCP-8634 cannot be transported into a containment cell. However, the area surrounding SCP-8634 has been closed to passage and is covered with iron bars. Entrance to the main building is prohibited unless permitted by Level 3 Clearance or above. Anyone within a one mile perimeter of SCP-8634 without the required clearance is to be forced out. This will be done by several guards working inside the area.
Description: SCP-8634 is a brick and wood house. Eight meters in height and fifteen meters in width. The exterior proportions of SCP-8634 do not exhibit any anomalous properties. Although when a subject enters the building, the interior's vertical width against the entrance is thought to be infinite in length. SCP-8634's interior is decorated with oldschool furniture. The types of furniture seems to display a pattern, which repeats in every 10 meters traveled into the residence. These will be referred to as "loops" from now on, for the sake of practical measurement.
SCP-8634 is harmless at first, but gets progressively more dangerous with each loop traveled. There will be more and more traps, toxic substances staining the floor, furniture becoming animate/hostile and even explosions which seem to occur out of nowhere (It has been discovered that these instances do not damage the house's structure at all).
In the first 30 loops, nothing particularly harmful has been percieved. Beyond this point however, these events will begin to occur more frequently, also with more severity. After a test conducted on a D-Class personnel (See Addendum-8634), it has been advised not to send anyone inside SCP-6834 unless completely necessary.
Addendum-8634: Below is an experiment involving a D-Class personnel (hereby referred to as D-4509) and several field agents investigating the site. D-4509 was given a high-framerate recording unit to track his journey into the building. The experiment has been documented as follows,
Control: Alright D-4509, you may begin the experiment, head inside the building.
D-4509: Its quite dark in here, the lights don't seem to be doing a good job at illuminating the place.
*D-4509 has traveled 32 loops, at which the subject pans the camera to the right and notices something*
D-4509: Uhh… what's all that black slimey stuff of the walls? And why are there spike-like structures scattered all over the floor now?
Control: Please do not inquire your surroundings. Proceed further.
D-4509: *Stops for a moment* Alright, fine. I'm really getting the creeps right now though..
*D-4509 travels 2 more loops, then suddenly stops and becomes slightly paranoid*
D-4509: Holy… this isn't safe at all. I need to look out for these traps now, I almost- AHHHHHH!
*D-4509 falls to the ground, clumps up and lies on the floor. Camera footage captures his bleeding right leg*
D-4509: Fucking trap! Why are they everywhere dammit? Arghh… that hurt a lot…
*Control commands D-4509 not to stop unless the injury is too severe, D-4509 continues*
*D-4509 travels for another 24 loops, then a blast noise is suddenly heard which knocks the camera unit away from D-4509. Subject quickly runs away deeper into the facility out of fear and panic*
Control: D-4509..? D-4509? Please return immediately. Disobeying will cause you to be terminated after the test is complete.
*Control calls for D-4509 for several minutes. Testing is then paused and teams are sent in with proper gear for recovery*
Recovery of D-4509 has proven unsuccessful. Loud yelling and screaming had been heard echoing throughout SCP-8634's interior for the next few days.
