Level uneven floor

Gti

My upstairs landing slopes down towards the bedroom doors by a quite noticeable amount so I'm looking for ways to fix/hide it.
We're down to bare floorboards in all the upstairs rooms and landing apart from bathroom. When there was carpet on the landing the airing cupboard door couldn't be opened all the way as the slope would block it.
The joist under the bannister seems to be set higher than anywhere else and I believe it sits on an RSJ so probably can't mess with it.
Ideas anyone?

I'm considering skimming down the floorboards on the higher side but it would need such a chunk removed I'm not sure it's feasible.
Could we build-up the floor level of the other rooms to match the height of the high point of the landing? We want to lay laminate in all the rooms and the landing. Would using extra underlay in the bedrooms make the floors too spongy?

This issue isn't the end of the world but while I'm renovating there's no better time than now. I hope someone has a good idea :T

On a first floor wooden floor?

The easiest way will be to reduce the one joist. You need to find out why it is higher first.

Ive done that before... in someone else' multi million pound house.

Nothing screams incompetence like screeding a second level wood floor.

OP, try your very best to avoid doing that, if needs must make sure theres no holes or you will regret it.

2 options.

1: Reduce the height of the offending joists so that all are level.
2: Increase the height of the other joists, either by sistering joists or by adding to the top of the joist

Using carpet again on the landing and shaving the bottom of the airing cupboard door is the cheapest option.You can put the landing work down for future investigation.I appreciate you want to crack the problem now but when do renovations go 100% right 1st time?

Taking up the floorboards and the bannister sounds like a lot of work...and there's already a lot of work we need to do here! Every time i strip back some bad plaster or look closely at the wonky doorway i die a little inside.
Doesn't messing around with structural integrity points like joists need planning permission and an engineer?

Airing cupboard door is already shaved down at the bottom. We had it in our heads we could take it up another half inch but it already looks a bit cack so were brainstorming for other ideas.

In regards to leveling up the floor I've realised while we could do it in the bedrooms which are down to the floorboards, the bathroom floor is tiled. As this is the only room in the house that hasn't been forsaken by the almighty i'm loathe to mess around with it.

You could level the floor using hardboard on part of it and then use a combination of

and

If there is enough area to cover, you will loose the variation in thickness, reasonably well.
