This has been reposted so many times. It’s obviously a work in progress, with the wood from the stairs missing. The floor doesn’t look finished as well.

I used to live in a home with a spiral staircase very similar in construction to the stairs in the picture. Once I removed all the wood in order to clean, fix and re-finish the wood. With the wood removed it was in fact a death trap like shown in the picture. I replaced the wood with temporary OSB cut to the right size, which actually looked kinda cool.

This is clearly a work in progress. The stair planks are meant to bolt onto those reinforcement beams, and likely a hand rail will appear for the last half of it.

In so much of this cookie-cutter “hip” newer housing, it’s either this or a dangerously steep angle, sometimes even both at the same time.

Enshittified architects building enshittified spaces thinking only of how it looks, not how it’s supposed to be lived in with safety and comfort from Day Two onward, the novelty wears off very quickly and you’re stuck with an unnecessarily, potentially deadly space.
