Hello,
our plot has a slight slope (2m (6.6 ft) over 35m (115 ft) length, but not evenly sloping) and we are currently considering how to arrange the different elements (house, storage/pantry room, carport) in terms of height differences. I would appreciate opinions or experiences regarding the slope of the driveway under the carport. We plan to place the carport 3m (10 ft) from the boundary line (more distance is theoretically possible but would interfere with other plans, so it should stay around 3m or less). Now the question is: what height difference can be managed over these 3m (10 ft) without making the driveway too steep? (The carport would be higher than street level).

We did something similar. The garage is located significantly lower. Our L-shaped retaining blocks behind the garage are 1.30 meters high (4.3 feet). From there, you can either take the stairs or the ramp without steps to the house. In between, we also have a slope.
Best regards

Yes, it will be similar for us too (with a different overall layout), although we have to overcome much less height difference.
I think you used the L-shaped blocks well... they don’t look as ugly as one might usually expect.

I think you used the L-shaped concrete blocks well... they don’t look as ugly as people often fear. Thank you very much for the compliment. I also believe that L-shaped blocks can be quite effective. Of course, they need to match the style of the house. Since clear lines and geometric shapes define the overall design in our case, they actually fit very well.
Regarding the height difference: we had to raise the house that much because we have a basement and wanted to avoid using a pump for drainage. Pumps can fail, but a natural slope always works.
Best regards

Mottenhausen11 Dec 2018 10:50House – high – garage – low is also a topic for us, but not as intense as for AxelH.
The house is fixed in the plan and indicated: located 4m (13 feet) from the street with the finished floor level 1.20m (3 feet 11 inches) above the curb edge. I want to reduce the height difference over the first 2m (6.5 feet), so a 50% or 45° slope (maximum allowed is 60°), then the remaining 2m (6.5 feet) distance should be level up to the house (with one step up to the door). That sounds okay to me as a layperson.
The driveway next to the house is 5m (16 feet 5 inches) long (so the garage is set back 1m (3 feet 3 inches) further than the house), and the question then is: how do we position the garage height-wise? Because of the terrain slope, it would normally be at the same height as the house, but that’s difficult because of the steepness of the driveway. Even a 1m (3 feet 3 inches) height difference over 5m (16 feet 5 inches) results in 20% slope... too steep for my taste! For a maximum 15% slope, the top of the garage slab would need to be at 75cm (30 inches) above the curb. But is being 45cm (18 inches) lower than the finished floor level of the house reasonable? I’m curious what the builder will suggest.
