Restore or remove glued parquet flooring?

In my little house built in 1958, there is parquet flooring in the living room and bedroom. Unfortunately, it is no longer in optimal condition. It is a light floor, variably darkened. You can see where the previous owner had their furniture. In the area in front of the terrace door, some elements are loose; overall, there are numerous gaps.

About 15 years ago, the parquet was sanded and lacquered once before. At that time, attempts were apparently made to fill the joints, which mostly did not hold for long.

I am strongly tempted to simply tear the whole thing out and replace it with wooden floorboards.

I just wonder what will happen to the screed if I tear out the glued floor? How great is the risk that I will incur even higher costs to renovate the screed? Can someone assess the risk? What worst-case scenarios are possible?

How can I find out if the floor can be sanded again at all? (apart from trial and error)

I would appreciate it if someone would share their experiences on this matter with me...

Show me pictures

Actually nothing, the floor adheres to the adhesive.

How big is the risk that I will then have even greater costs to renovate the screed? Can someone assess the risk? What could happen in the worst case?

It may be necessary to remove the adhesive from the screed using a renovation grinder.

Thank you, Sigi,

yes, pictures would be a nice thing, unfortunately I only have some from the sales brochure and of course he looks magnificent there. I will try to photograph the weak spots next week.

But I understand you correctly that no major damage can occur when tearing out? That it would be effort, I understand. :-)

Can one reasonably assume that afterwards, if necessary, one can have a level screed with some leveling compound, on which one could lay floorboards?

Again about the option "sprucing up". I actually don't like painted wooden floors, so I would want to sand it down anyway and then oil it, but that assumes that the parquet still has enough substance to be sanded again. Ok.. here we are again at the topic of photos....

When you write

In the area in front of the terrace door, some elements are loose, overall there are numerous gaps.

I wouldn’t fuss around with it for long, but rather tear out the old stuff and do it new. I think renovation work will be necessary anyway and it could be done at the same time.

My feeling says the same. Once I’ve moved in, the effort for that will be much greater.

But then a whole series of follow-up questions come up:

If the ceiling height is already only 236 cm, how do I get a nice wooden floor without losing too much height?

Floorboards are nicer than parquet, at least for me. But a substructure is out of the question, because of the total height and the transition to the tiles in the kitchen and bathroom.

Is it possible for a layman, with a prospect of success (i.e., more success than the parquet layer 50 years ago), to glue down a wooden floor firmly?

Noise from impact sound is definitely an issue in the house according to the previous owners, so floating installation won’t be a good idea, right? ([Klammerdielen])

Next question: If floorboards, then in all living rooms, but individually, with a finish at the doorways, or continuously, basically in one piece? Does that make a difference in terms of impact sound?
