This is specifically for sector 1 of light containment zone (safe, low risk, low disruption SCPs only).
To me the hallway looks pretty bland, and I was wondering how I could make it less boring.
but yes it looks bland and you only shared 1 image so it’s hard to make more feedback
it looks a little colorless (even though SCP facilities tend to be more colorless) so take inspiration from SCP site phoenix map (the new game, but you can take inspiration from the old game too)
the SCP 330 there with the black thingy is very black maybe tune it up or use other colors also in it’s door you could add his “safe” class somewhere to add detail there
Reminds me of when I first started making SCP facilities as a builder. Depending the style you’re trying to go for, sci-fi or more industrial, the colors help instantly make a simple area and/or design look better.
While SCPFs loving using a dark, monochrome and gritty style of both colors and aesthetics, I suggest changing one of the larger wall stripes, preferably a more unique color that’ll also help differentiate each sector. Since Sector-1 is a safe, more common area, I suggest something more of a washed desaturated green, nothing too vibrant.
(color not for reference, just where it should applied)
I wouldn’t recommend any props within this hallway as it seems from the screenshot that it is a bit narrow, however stuff like alarms, speakers, posters, plants or even some seating arrangements along the wall would suffice pretty well. Barriers can also be applied when applicable if Sector-1 is going to be a hotbed for hostile activity (which is doubtful) as well.
Wall decoration: Posters, alarm lights, etc.
Color: As previous two posts suggest
Props: Storage shelfs (you’ll need to level out the floor in that case)
You could also add actual purpose for dead-end hallway, like adding storage room, another scp or any other relevant room at the dead-end. Depending on layout you have, you could also make some kind of bigger, open area for cafeteria or general living space on the right-side of the picture.
Just curious, do you have already planned layout or is this just showcase?
