Hello,
I suspect that the joist or core wall construction in my townhouse from the 1960s is not sized for the bathroom with a self-leveling floor including underfloor heating installed in 2015.
The suspicion is because the entire upper floor (see floor plan), where the bathroom is, slopes toward the middle of the house and especially toward the bathroom. In the bedroom next to the bathroom, we have a difference of up to approximately 70 millimeters from the wall towards the neighbor to the wall towards the bathroom.
The ground floor is built on a crawl space with a concrete slab, which I assess does not show any signs of sloping (see photograph), and the construction is otherwise in wood according to the building permit documentation (see photograph).
How should I proceed if I want to have the slope corrected and above all prevent further sloping?
Who should I contact and what might it cost roughly?
Thanks in advance!

It is best if you contact a structural engineer who can look at your house and provide suggestions. The question is whether the slant has been caused by the extra weight in the bathroom or if it is another issue. Then the next question is how to rectify it if that's the case. Whether it is possible to lift and support it in some way from underneath, or if the bathroom needs to be relieved, restored, and replaced with lighter materials than what is currently there. A price estimate is impossible to give since it could involve one or several actions that are difficult to speculate on here.

The price range can vary greatly in different parts of the country, but you can contact 2-3 practitioners in your area for a price quote.
