Hello everyone,
We are making steady progress with our architect. The floor plan is already looking very good.
Now we have been asked which type of floor slab we want to use for the upper story.
Concrete slab or timber beam ceiling – what are the advantages and disadvantages? Can anyone comment on the costs?
For context: We are planning a solid masonry house with calcium silicate blocks and facing bricks. Footprint: 12.5 m x 9.5 m (41 ft x 31 ft);
2 stories with a roof pitch of 30°.
Best regards, Barossi

Hello,
yes, that's correct. Our architect asked what type of ceiling we prefer: wood or concrete. That’s why I’m asking about the advantages and disadvantages. And why didn’t you return this question to your architect? He can hardly expect you, as a layperson, to understand, evaluate, and answer it.

It is simply more complex to install underfloor heating above a wooden beam ceiling and to adapt a concrete slab to the roof rafters. In the case of the original poster, it seems to be an urban villa, whose top floor would make more sense to build as a wooden beam ceiling. A 30° roof pitch is not exactly ideal for converting the attic, unless a loggia is planned in the roof.
Ultimately, the budget and the structural engineer will decide between wood or concrete; concrete as a floor slab above the upper floor is more expensive. For the size of the house, additional costs of around 5,000 euros can easily occur.
He needs to decide how the floor will be used AND consult with his structural engineer whether a concrete slab is actually necessary.

Hello,
thank you very much for your reply. The crawl space is intended only for storage (children’s items, suitcases, etc.). No conversion or finishing is planned.
In that case, a concrete slab between the ground floor and the upper floor would be advisable, and a wooden floor between the upper floor and the attic, correct?

Hello everyone, I’m joining in here because we have a similar situation to decide on.
- Solid construction, two stories, 27° roof pitch, hipped roof.
- The attic will only be used as storage space and possibly for the ventilation system.
Sound insulation would only be relevant because of the ventilation system. The roof, not the ceiling, is going to be insulated.
Upper floor ceiling: concrete or wood?
Are the costs necessarily higher with concrete?
I would appreciate hearing about your experiences.
