I have a question about the floor construction of a timber beam ceiling and hope this is the right place for it!
About six years ago, my father added an extension and an additional floor, but the upper level is still a “shell.” The area in question is about 10x10m (old house) and consists of a timber beam ceiling with 6x20cm (2.4x7.9 inches) beams spaced 50cm (20 inches) apart. Currently, a 2cm (0.8 inch) plywood/OSB board lies on the beams. The goal now is to level the floor structure to match the height of the newly built areas (the house was extended on two sides). The current height difference between the new construction and the OSB board is 6cm (2.4 inches).
My main concern is acoustics, as the floor should be insulated as well as possible to minimize the transmission of footsteps both within the apartment and to the floor below.
Attached is a picture for illustration.
My preferred option is “Situation 1” because it allows me to add the most material and volume. Although it involves more work, I’d rather do it properly than regret it later. However, I have a big question about how drywall partitions would be installed here. Would these be screwed directly onto the beams first?
Regarding “Situation 2”: It is obviously simpler since the OSB boards can remain as they are, but the floor build-up is not as high. Only about a 3cm (1.2 inch) loose fill can be added, with the rest being compensated by drywall floor panels.
For your information: A structural engineer and various craftsmen will definitely be involved for assessment, but I want to get a preliminary idea of who might be misleading me and who really knows their stuff.
Which option is the most sensible? I am very grateful for any other suggestions, ideas, or advice!
Thanks in advance and best regards,
Phillip

But isn’t that way too little?
At the moment, when walking on the floor, the entire ceiling vibrates slightly. Not strongly, but you can definitely notice it. If I then just put "Styrofoam boards" and a dry screed on top, nothing will change about that, right?
