The house was built in 1957 and was completely modernized in 2012.
Among other things, the basement ceiling was insulated and underfloor heating was installed. As a result, the room height on the ground floor shrank to about 220 cm (clear height).
If you can cope with the 2.21 m yourself, I would worry less about that than about the execution of the work during the renovation. It is absolutely unusual in an old building to reduce the room height by so much. Are the ceilings perhaps additionally suspended?
Anything built after 1950 should actually come with a raw construction height of more than 2.40 m on the ground floor. That would mean that the floor construction, despite having a basement, is at least 20 cm thick. Is it visible somewhere (basement stairs, entrance door, terrace door, for example) how much was really built up? Was the basement ceiling insulated from below?
The sill height (height of the windowsill!) is certainly not between 1.10 and 1.30 m, otherwise the windows would be less than one meter high and would really only start at "chest" height. A normal height is rather 80-90 cm. It’s best to measure again. I assume the doors are 2 m high?
