1960s home build, floor issues (level)

[MINS]

Hello everyone, hope all are well and safe.

I have a home which was built in 1960s, the living room and dinning room were seperate rooms but in 1969 the wall was removed to be open plan (I know this as someone dated and signed floor 1969 wall removed under carpet!).

Trouble is the floors are not level, this was clear with carpet over, there is a little change and slope visibility. I want to fit laminate floor through out, but fitters said I need to sort the change in level. When I initially bought the home I recall the owner explaining they wanted laminate for years, but never did due to the task and difficult in raising the floor level.....

I'm also struggling, but won't give up! Initially I thought a chippy would be able to square off the floors with a sort of wood threshold with laminate meeting each side with a step... But getting a chippy to do it seems nigh impossible.
I've discussed self leveling but worried the whole floor will need raising on the one side which would then affect the step between halwayy and kitchen...

Thought about a chamfered skirt or similair to remove the slope and square it off but don't think I would make it work as it's sliglhty diffrent levels fro. One side to the other. So hard to explain in text.

Not sure where to begin, I guess a specialist but it's been torture just getting them. Round or interested. Rather sort it myself and then get floor fitted.

Maybe I breakout the middle section and form a new squared off step, the laminate fitter said he can then cap ends that meet the step etc. I don't mind a step as long as I can sort this tbh.

Not a floorer

but in houses that were built with separate floors in each room (solid) it’s reasonably common.
In that instance, it was not an issue.

so you have the issue of raising or lowering one floor

to be honest, I would work out a way to reinstate the finger parquet with reclaimed and a floorer could probably do it, but you want laminate.

you could possibly lift the higher parquet entirely, dropping one side by at least the thickness of the bricks? I am guessing 10-15 mm?
Then apply levelling compound over it all?

Their very very thin about 2 to 3 mm.

The parquet is pretty ugly tbh god knows how unven it is under, an was to. Leave and laminate over.

My mistake.
It looks like vinyl tiles, I didn’t open the pictures.
You have the option of removal of the higher ones (may contain asbestos in low amounts)
Then have the floor ground down to reduce the slope
Then levelling compound

When I ran a joinery shop I used to make thresholds like this fairly often for carpenters.

I’ve done them upto 300mm wide and going from say 8mm to 40mm

A jig on a thicknesser can do it, but it’s not really something site carpenters can do - it’s pretty hard to machine accurately without joinery machinery.

Thanks. Would I be able to leave the tile covers and just use self leveling for the whole lower floor and be done with it?
