Simple way for hanger attachment / securing

Tomorrow I have another appointment with the landscaper and am still looking for alternatives for slope stabilization... Mainly, it's about the second picture where the area towards the neighbor with his garage is supposed to be retained. On our side, about 10-15 cm will be added on top, which we would effectively raise, while the neighbor basically excavated from his garage door to the street.

What is the simplest and most effective way to do that? So far, either L-shaped concrete blocks or a wall made of shuttering stones along the neighbor's driveway and around the corner into the boat have been suggested by the landscapers who were on site. Where the 2 cars are now parked, a double carport is supposed to be built later.

What else comes to mind are planting stones or gabions filled with gravel?

The appearance is secondary for now; it is primarily about securing the thing...
The section of slope along the street is to be bordered with curbstones and then planted with some kind of rampant plant/ground cover

Hello

L-shaped stones are ideal for this. Reinforced. 60cm should be sufficient.
The most cost-effective way to permanently stabilize the slope. and manageable with 2 people. In case a mini excavator cannot be operated.

You must not catch anything, it will hold on its own. Save your costs and plant a few plants.

You can: - do nothing and let it grow wild - build a concrete wall and everything in between. I would plant the slope with bushes that only need to be maintained once a year. In return, you get some greenery and a nice view.

But I do have to edge the cobblestones that will be laid on top (about 20 cm more will be added), so would curb stones 6x20x100 extending from the neighboring garage towards the street be sufficient to border my paving? How far do I then have to stay away from the boundary, since the garage is practically on the boundary? So I stay so far away from the boundary that the concrete wedge for fixing the curb stone practically ends at the boundary?

That is also not a problem as long as you do not want to extend your area up to the property boundary. For a stable slope, 60 degrees with vegetation are sufficient. With your concrete, you remain on your property unless you arrange otherwise with your neighbor.
