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.
No way, it has splotches and a big unfinished ragged seam. The wall facade is also floating about an inch of the floor. This is most definitely not a finished floor.
Not finished concrete at all, this floor is completely unfinished for a what looks to be a residential space.
You would have a polish, sheen, etc. to the concrete, this just looks like what normal subfloor would look like before you put down tile, hardwood, carpet, etc.
My basement floor looked exactly like this after we pulled up the carpet before we put down hardwood.
I don't think is a WIP, the light fixtures are usually the last work they do to avoid broke it while doing other jobs and here there already functional.
The lights are embedded in the wall and the stairs are fixed to the wall. So they probably wanted to finish out the wall before they put in the stairs. The wood of the stairs would also need to be fitted to the wall exactly, so it makes some kind of sense to finish the wall first. I would have opted for little nooks for the stairs to fit in, but there were probably reasons that didn't make sense in that situation.
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.
I'm a handyman. This will not pass an inspection because it lacks the handrail necessary to be code compliant. That's before even getting into tread width and lack of trip resistant rise.
They might vary on issues like how high a riser or how wide a tread should be but if they are going to bother to have a code then they will usually contain things like the need for a railing.
In most cases you'll need an inspection when you go to buy a home. Anytime you're changing a house you have to ask yourself "Will this hurt the ability to resell it later on?" This is going to end up on an inspection report and it's either going to have to be remedied or it's going to drop the value.
Linoleum. He won't go down to the landing to the basement. He'll do one, maybe 2 steps. So that's where I keep his food. Even if I forget to shut the door, he won't go down there and annihilate the bag.
Meanwhile, my dog is so stupid, he'll jump onto slippery vinyl floors from couches and chairs. I've actually seen him slip, fall sideways and body slam into the ground. I found him limping one time and I'm reasonably sure it was from jumping off the couch, which is when I finally put my foot down and blocked him from jumping up onto it. Built a little ramp instead.
