Hello.
We worked out a very nice floor plan (at least for us) with an architect. In this plan, the utility room would be located in the northwest part of the house, behind the garage. The utility lines come from the street to the west and would be routed beneath the garage. Generally, such lines are apparently not allowed to be covered by a garage. The architect suggested that the lines could be installed under the garage if no concrete slab is poured inside the garage, but instead gravel is used as a base, and then paving is laid on top. This way, the utility company would still be able to access the lines if necessary. I contacted the utility company today, and they confirmed that what the architect said is fine and the lines may be covered by a garage in this way.
What do you think about this idea?
The next question is... if we proceed with just gravel and paving, without a concrete floor slab, what about moisture, especially humidity inside the garage? I have already read through some forum posts and found some people who also wanted to build a garage without a floor slab and were uncertain. We would like to put up shelves in the garage and store various items such as Christmas decorations.
I’m interested to know if anyone has already built a garage like this and if you experienced any moisture problems. Also, what has been your experience regarding storing items like Christmas decorations or similar? Is storing such things possible on a non-concrete floor, or does everything get damp?
Looking forward to your experiences on this.
Best regards

Regarding the foundation slab: If only paving is used, the horizontal waterproofing that is usually welded onto the slab will be missing. This will result in permanently higher humidity levels. The severity of this "issue" depends on the soil conditions and how well your garage is ventilated. However, you could also install a vapor barrier membrane beneath the paving, which would likely be an equivalent solution.
