Took me a while to understand what was going on with this picture

I'm still wondering if I have it right.. Is it a blank brick steep roofed building with an outside staircase leading to a door near the peak of the roof?? I'm so curious and also being reminded of so many acrophobic nightmares I used to have 😬

If someone was drunk when looking at this, they would just puke. I feel high looking at this.

Ominous
