Hello everyone,

I would like to know at what height I should set the foundations in the working area (right next to the house) for the carport? Top edge of the basement ceiling / bottom edge? I assume the height of the paving stones and so on still needs to be deducted here! Correct. But what measurement is usually used in this case??

Thanks for your tips and experiences!

At our neighbor's property, the foundations are located below the paving. The entire paving of the parking spaces is drained internally, so the paving stones are at a different level than the basement ceiling.

That means the height of the foundations equals the floor slab top edge minus the height of the paving stones minus the gravel layer for the paving stones...? Would that roughly be the standard reference value?

With my neighbors, yes, although the gravel layer above the pad foundations was significantly thinner than under the rest of the paving stones. When they wanted to build their carport, they planned to remove the paving stones (above the foundations) and set the structure directly on the foundation. In other words, the post of the carport extends down (deeper than the paving stones). It’s a matter of personal preference whether you find that more visually appealing...

I understand the raw floor surface level as the target finished floor level.

Yes, the rough floor surface is meant as the target finished floor level 🙂
Since we have not yet agreed on a specific paving stone, what height should I assume here? 7 - 8 cm (3 - 3.2 inches)? Thickness of the gravel layer?

Thank you

Gravel layer about 4 cm (1.5 inches), paving about 8 cm (3 inches), settlement approximately -1 cm (0.4 inches).
I think it makes sense to place the carport directly on the foundations.
If you want to hide the foundations, set them about 10-11 cm (4-4.3 inches) below ground level – but then you will need appropriate ground sleeves when assembling your carport. Otherwise, set the foundations at the final level and pave right up to them. This can also look quite nice. It’s really a matter of personal preference – do you want to see the "ugly" foundations later or not.
