Hello dear forum community,
we need to build two retaining walls, each 80 cm (31.5 inches) high, along the boundary with our neighbor to support our two parking spaces. The development plan states that retaining walls are only permitted up to a maximum height of 80 cm (31.5 inches) and must be constructed as "dry walls" (without mortar or adhesive). I have already found out that dry walls do not necessarily have to be made from natural stones, as long as the stones are neither glued nor mortared together. Additionally, the estimate from our architect is only about one-third of the price quoted by the landscaping company.
Unfortunately, my partner believes that support with plant bricks, which can also be built by oneself, is insufficient to bear the load of two cars.
Now I am wondering if the use of angle blocks would be possible, and whether this would still be considered a dry wall since the individual blocks are also not glued or mortared together, and a dry wall can be built from concrete masonry units.
So far, I have avoided asking the municipality to prevent them from insisting on natural stones.
Thank you all very much for your opinions.

Definitely get it in writing! Since you mentioned that you originally wanted to do it yourselves because your wife dislikes planter blocks, you can also install L-shaped retaining wall blocks on your own. However, it is highly recommended to use a mini excavator for this, otherwise you’ll end up exhausting yourself with the heavy lifting.
