ᐅ I urgently need your advice.

Hello everyone. I’m new here as of today.

Here’s the situation:
We want to build a bungalow this year, and it’s very important to me that there are no steps anywhere inside or around the house.
How deep can the foundation slab be set compared to the garden level?

A few details to help you picture it better:
My plot has about a 60 cm (24 inches) slope from the highest point down to the front door, and about 60 cm (24 inches) from the highest point to the terrace. The slope continues downward beyond that, so I will have to add a lot of soil around the terrace and entrance. That’s why I want to keep the foundation as low as possible.

Unfortunately, the builder says "you don’t put a foundation slab directly in the dirt," so he wants the top edge of the slab to be level with the lawn surface at the highest point in the garden.

What do you think about this?

It’s urgent, because the excavator will arrive on 16.01.2015.

Oh, the eaves height depends on that. I need to check what it refers to in our case because the nearest street is just a dirt track, and there is no gutter or anything similar there. The second-nearest street is already quite far away again.

@knochi3 Sometimes there is also a marking on the next streetlight.

@Bauexperte After the building permit / planning permission was granted, our structural engineer noticed that the purlins need to be a bit thicker, which will make the house slightly taller. The surveyor says that this isn’t a problem.
However, we don’t have any regulations regarding eaves height.

So I reviewed everything carefully again and found that there is actually no specific eave height requirement for us, only a maximum eave height of 6.5 meters (21 feet 4 inches) imposed on my and the neighboring property, which we definitely stay below.

Now that everything is clarified, I would like to ask again if you agree that the slab should not protrude completely above ground level, but rather be recessed into the ground with only 5 cm (2 inches) visible above the surface.

It would also be interesting to know at what height your slabs are positioned compared to the surrounding ground level.
But please consider only the slab itself and not the floor structure above it.

What exactly has been clarified? That seems contradictory.

Oh man, this really isn’t any help. Let’s put it this way: I honestly don’t care whether it’s legal or not, and I don’t want to debate that any further. I’m sure the permit is fine on that front.

Besides, I don’t see any contradiction in the quote. There is no specified eaves height for us, only a maximum that we are allowed to be under, which we are.
