3-4 m terrain jump sounds like a hillside property. Is the house already planned or even built?
Is a strip foundation necessary at all for a small wall?

Slope property yes, the slope goes upwards. We have already built a hall into this slope and there is currently a 45-degree slope up to the natural terrain. Our future garden is supposed to be on top of the slope. The house is planned and will be built soon. However, the house will not be built where this wall is supposed to go. Also not on the slope. So it doesn't affect the whole thing. The ground floor is also set into the slope at the back. The stones have a static load capacity: the 40 cm can support 1.20 m with a 15% embankment above. At 60 cm width 1.80 m and at a width of 80 cm, 2.5 m can be supported with embankment. So we need a thicker stone anyway. The 60 cm stone also weighs 2 tons each. According to the static calculations, they are simply set on 032 and compacted with a layer of gravel or lean concrete to make it level.

What you are building is not a small wall. Drainage and frost-free foundation are important. Whether it has to be a foundation, I would question. Surely something can shift there - so if it is supposed to stay perfectly straight, the effort is correspondingly higher. The earth mass becomes a problem when it is completely saturated with water.

I'm not asking about the effect on the retaining wall but about the general planning. How steep is the slope in the area of the house? Standard house planners often plan by leveling the property, which often leads to an expensive awakening. It is rarely planned with the slope.Yes, it is a sloping plot, and the slope goes upward. We have already built a hall into this slope, and currently, there is a 45-degree slope up to the natural terrain gradient. Our future garden is supposed to be at the top of the slope.
The house is planned and will be built soon. However, the house will not be built where this wall is supposed to go, nor on the slope. So the entire thing does not affect that. The ground floor is also embedded in the slope at the back.
The stones have a statics: the 40 cm block can hold back 1.20 m with a 15% slope above. At 60 cm width, 1.80 m, and at a width of 80 cm, 2.5 m can be retained with a slope. So we need a thicker stone anyway. The 60 cm block also weighs 2 tons each. According to the statics, they are simply placed on 032 and compacted firmly with a layer of grit or lean concrete to make it level.
You also need a much flatter slope on top. The Lego solution is probably not the best idea.

Yes, the house will be set into the ground, just like the hall was a few years ago. From the southwest, the lower floor is practically not visible. Our garden will then be on two levels, with the first level being the same as the upper floor and the second level a bit higher. We want to dispose of the excavation as much as possible behind the wall.
I have also attached an old photo of the hall construction in which you can see the current slope. I have drawn in the planned wall and the new terrain profile. The house is practically where the photo was taken back then. Approximately there, one will later stand in our dining room on the upper floor.

As the retaining wall is drawn in the photo, it could work. Why not with L stones? Ok, the house is quite well planned with the slope.
