Shit. I really should've taken photos of the weird rooms in my late Grandparents house. It was a Duplex and they bought the other half of at one point to house their 8 kids. Haphazardly stitched together into one house with three door rooms or extra staircases all over the place thanks to being 3 stories tall with a basement too. Quite small sqft per floor however.
The pink and black tile makes me think somewhere between the 50s and 70s, then you've got the 2000s titty light minus its globe and CFL bulb, which apparently isn't where the light is coming from.
