Plan courtyard entrance (house already exists)

Variant2:

House entrance with platform at finished floor height, then driveway in the carport area down to the entrance at -0.18 with a slope away from the house of 2%. From the entrance, uniform slope to the street also with 2% cross slope. Execute a channel in front of the street and install an inlet at the lowest point.

The version by is by far the best technically. Visually, I find it very boring, but of course that is a matter of taste.

Currently, I would prefer the option with the arch in terms of appearance (so the first picture), it might also be more cost-effective. Technically, option two is probably the cleanest. Well, back to the drawing board tomorrow...

The width of the driveway in option 1 should then also be optimized. 3 m is sufficient.

For me, hand sketches on graph paper are also enough. ;)
