ᐅ Is it possible to install L-shaped concrete blocks at varying depths?

Hello,

we are currently planning the outdoor area a bit.
To avoid embarrassing myself with certain companies due to my question, I thought I’d embarrass myself here first.

Our driveway is on the right side of the property (garage built on the boundary) at street level. The street slopes downward slightly, so our right neighbor’s property is lower. The driveway up to the garage is 7m (23 ft). At the front, from the street, the height difference (top edge of planned paving to the neighbor’s lawn level) is 30cm (12 inches). At the garage after 7m (23 ft), it is almost exactly 1m (39 inches).

We want to retain this height difference using L-shaped retaining blocks. Should I assume the highest block height (at the garage) and extend that height all the way to the front? Or is it common to place the L-shaped blocks side by side at different depths?

I hope you understand what I mean.
Attached is a picture.

Looking forward to expert advice.
Best regards, Flo

Hello

In my opinion, asking questions usually does not cause embarrassment.

To the point: I would subtract the slope of the area from the garage to the street and then set all the L-shaped concrete blocks at the same height.

Hello

Stepped design.
There is a significant difference in both cost and complexity depending on whether you use 50cm (20 inches) or 150cm (59 inches) L-shaped concrete blocks.

Who was responsible for this detail with the gutter on the flat roof oO...

On the topic: you can either do both options or use L-shaped elements with different heights.

Height differences of 30cm (12 inches) with the same L-shaped retaining walls can also be compensated for through the foundation. A stepped design is a nice solution; slanted L-shaped retaining walls are not.

Regarding the flat roof gutter: Haha. That’s also a solution.
