Driveway planning for large sloped property - 25% gradient

Detective has struck again.

The thing with the "green strips" is a bit of an issue anyway. I'll talk directly to the city about what can be done there. The development plan is still "quite" new, and I think it was simply an attempt to bring the existing situation into a proper planning form. Many of the requirements have also not been implemented by (newer) houses. I hope we will also be able to get some exceptions here and there.

is right too! The garage really doesn't have to be on the summit cross, and the base camp should be enough. I just didn't quite understand the thing about the curve.
If the curve has an incline at the same time, it's not quite as extreme (meaning the curve itself)?
Does anyone happen to know what radius or diameter such a curve with an incline is allowed to have?

If the curve has a slope at the same time, it is no longer quite as extreme (meaning the curve), right?

I didn't think so, but of course it's also true: that "Pythagoras" also works in three dimensions applies just as much to curves as to straight lines.

Depends on your car; T-Roc has a turning circle of about 11m; but there are also turning circles of 13 and more; a Smart can manage it with 7m.

The steeper the road, the tighter the curve, the faster you end up in the ditch in winter, downhill; when driving uphill, most get stuck in the steep curves... I also have flatland Tyroleans here who simply cannot drive narrow mountain roads.

If it gets too steep, there should be a buffer stop in the curve

How about a straight driveway with a turning area (red), carport (black), and a staircase (blue) to the house? The turning area, of course, would be level...

€: The road could essentially be dug into the slope. On the uphill side, supported with a concrete wall or L-blocks, and on the slope side, slightly sloped. The resulting triangle could then be planted.

€2: On the L-blocks, a hedge could be planted as a privacy screen to the garden.

And to shorten the walk to the house, you could also make a staircase from the street to the turning area. That could be pretty cool.

Detective @Escroda has struck again.

Yes, I'm always so impatient. I simply couldn't wait until Christmas.

How about a straight driveway

With 6m road width, the property would hardly be accessible from the north. Well - it's not a federal road - a bit of maneuvering is definitely possible, but it would be inconvenient.

Carport (black)
