ᐅ Semi-detached house – Which type is best? Does anyone have experience with this?

Hello everyone,

I am currently considering building a duplex and am looking for ideas on how it could or should be constructed to ensure a sustainable building in the long term. Of course, it also has to remain affordable.

On the internet and from building planners, you often hear that "this particular method" is the best, depending on the preferences of the contact person. Perhaps someone here can share how they built theirs or what could be done better or differently, so I can get a clearer picture for myself.

Thanks in advance to everyone who takes the time to help!

Best regards,

Partition walls between houses are always double-layered anyway

Between residential units, this is not an issue. In that case, the slab on grade simply needs to have a continuous joint (meaning two separate slabs). The problem I mentioned relates to impact sound transmission within a single residential unit. This becomes even more critical when the building is constructed with a timber frame rather than solid materials; keyword: flanking elements.
However, for two semi-detached houses using this specific construction method, I would seriously question the budget.

Isn’t this possible with concrete as well?

The usual suitability test for floor coverings using the CM measurement is not applicable. As far as I know, there are no guideline values for floor covering suitability testing on concrete substrates either. You can’t equate screed drying times with concrete drying because the processes are completely different. Resistance measurement is also not feasible since the reinforcement significantly distorts the results.
A capacitive measurement method might still be possible (though likely inaccurate), as well as a destructive material test, but in that case the test specimens must be taken dry.
