Inconsistent rise in stairs

[yayalon00]

So we noticed the first step in our stairs is significantly higher than the rest of the steps.
The first step is >230 mm and the others are around 190mm.

Developer says it's fine because we don't have carpets in the ground floor (so the transition is from hard floor to carpet).
But we have another transition in the 1st floor to the stairs leading to the 2nd floor and the rise of that is consistent throughout.

I have checked the LABC technical manual and the maximum rise is 220mm so it's almost 1cm over the max rise.

Of course my concern is that I let this go and 30 years down the line this becomes a major headache when selling the house.
Advice? Other than rebuilding the whole staircase structure how can the builders fix this?

IT seems to me something didn't do their maths right.

I would guess the the joist height is wrong and the stairs have been jacked up . Either way there is no easy fix .

Al, stair risers (steps) should be the same height from a safety point of view.
This is irrespective of the type of floor coverings used.
It is also a Building regulation K1 1.5 "the rise and going of each step is consistent throughout"
Domestic stair rise should be 150mm min to 220mm max.

The easiest fix would be to lay some latex to the ground floor to reduce the rise of the first step.

Thanks for your message. We have so many issues. So many issues.
I'm a doctor. Can you imagine if I was as shoddy as the builders that built my house?

I suppose the new build ombudsman is nowhere to be expected any time soon.
I'm at a loss..  It's as if they had to strip the entire house and rebuilt it.

We installed LVT throughout the house, but the floor boards aren't properly glued to the joists, so they need to lift them all up.
Now with the stairs, I assume they would need to strip the entire ground floor as the latex would go under the LVT?

How can these builders be so bad?

It sounds like some kind of nut job did this. That's highly unprofessional and dangerous. Any way to sue the guy or company? I can only imagine how you feel about this situation...

To build up 40mm on the floor will be a nightmare , you would need to do the whole ground floor , skirting,  doors etc

Fitting a new staircase wouldn't be any easier either.

Fitting a new staircase wouldn't be any easier either.

The problem here, is that they made a mistake when measuring and ordering the current staircase. And instead of fixing it, they hoped I wouldn't notice.
Our mistake was to notice after we had moved in.

For example my uncle had a issue with his stairs in his new build, but the developers decided to make it right and he was only told after they had fixed it.

On the other hand his developers/builders failed to insulate the roof and that cost him a fair amount of money down the line.
So I guess we'll have to live with it and perhaps only consider fixing the issue if in the future we decide to re-do the floor.

Another thing that annoys me is that I was hoping to be able to replace the carpet on the stairs with something different, a wooden staircase. this issue might make it much harder as the higher rise in the first step will be even more evident (and dangerous) without carpets.

It would be useful and helpful for others visiting this forum if you name the housebuilder.
It also demonstrates the value of having your new home professionally snagged and inspected before you legally complete.
