ᐅ Concealing concrete, separation in gravel area

Hello everyone

We have installed curbstones around our house, positioned 30cm (12 inches) away from the facade.
Between the facade and the curbstones, we are filling the space with decorative gravel. It fits well and looks great.
On the terrace side, the curbstones are placed 75cm (30 inches) from the facade.
Due to the slope of the terrace and other planning considerations, we had to raise the curbstones by 10cm (4 inches).
This also meant that the concrete wedge alongside the curbstones had to be raised by 10cm (4 inches).
Now we are filling the gap again with gravel.
Unfortunately, the gravel is only allowed to be filled up to 20cm (8 inches) below the facade.
That’s not possible since the concrete is higher...

Our advantage is that only the first 30cm (12 inches) from the facade towards the curbstone have to be 20cm (8 inches) below.
We are now thinking of raising the gravel only in the area of the concrete wedge. But how can we best separate the different gravel heights? I don’t want to add another line of curbstones.
Something simple and cost-effective would be great.

Nice backrest. However, it is unfortunately unnecessarily high for the corner you described.

That said, I haven’t quite understood your pictures and description yet. Sorry. Where exactly is the terrace, where are the stones higher, and what does the heat pump have to do with it?

Thank you for your feedback.
A brief response to your question about the heat pump:

1. The first photo is just an example showing what we mostly already have. It fits perfectly there.
2. The second photo shows the problematic area along the entire length.
The front 3 stones are 20cm (8 inches) high. The backrest is 5cm (2 inches) high.
The rear stones are 30cm (12 inches). Here the backrest is about 9–10cm (4 inches) high.

I thought the backrest should be about one-third of the total height.
The change from 30cm (12 inches) to 20cm (8 inches) stones occurred because we have a 6cm (2.5 inches) height difference due to the slope.
This problem only occurs here since this row of stones is 8cm (3 inches) higher than everywhere else around the house.

"Should" is exactly right. Not a must.
I would significantly reduce the amount of reinforcement and focus more on leveling. The edge strips practically experience no load; a few centimeters (inches) more gravel won’t affect the house.
