Hello dear forum members,
we are currently in the planning phase while waiting for the building permit / planning permission, and now we are focusing on the planned floor structure. We are building with a basement, and the basement floor is specified by the thermal insulation certificate and should remain as planned. However, we are not completely sure about the intermediate floors to the ground floor and attic. Underfloor heating will be installed everywhere. We are not planning a ventilation system or central vacuum, so only the usual water and electrical pipes will be laid on the concrete slab.
1. Basement slab: Concrete _2400 250mm (10 inches), PS-035 impact sound insulation 140mm (5.5 inches), PE film 0.20mm, cement screed 50mm (2 inches), tiles 15mm (0.6 inches).
Here are my first questions: We originally planned to use self-leveling screed. Does the thermal insulation certificate need to be adjusted for this, or does it not matter which screed is used? Will the self-leveling screed also be installed at a thickness of 50mm (2 inches)?
2. Basement ceiling / ground floor slab, the architect plans: concrete ceiling 200mm (8 inches), floor buildup 180mm (7 inches).
My questions here: What would be an optimal floor structure if we plan tiles almost everywhere on the ground floor as well? Laminate will be installed in the guest room. We are uncertain about the 180mm (7 inches). Isn’t that too much? Wouldn’t a buildup of 150mm (6 inches) also be sufficient? For example: concrete ceiling 200mm (8 inches), impact sound and thermal insulation 85mm (3.3 inches), self-leveling screed with underfloor heating 50mm (2 inches), 15mm (0.6 inches) tiles or laminate.
3. Ground floor ceiling / attic floor slab, the architect plans: concrete ceiling 180mm (7 inches), floor buildup 160mm (6.3 inches).
Here is our proposal for the exact floor structure: concrete ceiling 180mm (7 inches), impact sound and thermal insulation 65mm (2.6 inches), self-leveling screed with underfloor heating 50mm (2 inches), 15mm (0.6 inches) laminate.
And a completely different question: What do you think of cork flooring with underfloor heating?
I would be very glad to receive opinions and suggestions!
Best regards, Kisska86

Well, maybe I see the homeowner’s role a bit differently. I don’t think I should only be involved in decisions about the floor plan, wall construction, finishes, and type of systems. We contract all trades ourselves, and I want to fully understand why, how, and what is being done... including the floor structure. And it is true that there is some flexibility there. The architect made their proposal, and we are evaluating whether it suits us or not... It’s well known that ten different contractors can have ten different opinions about the same thing...
By the way, in another forum I received suggestions for possible floor structures and I am grateful for that. Now we will continue to evaluate...

Once again, my advice: Talk to your architect and ask exactly these questions. Afterwards, you will either be satisfied (convinced) or start to have doubts about their competence. The latter is probably not a good foundation for collaboration.
As the building expert already mentioned: As a client, you certainly have meaningful input in many areas, but to be able to contribute to something like the "optimal" (I still find this word hard to say) floor construction, you simply don’t have enough overall understanding of the topic.
Good luck
