Earth alignment

We want to level our garden.

Length of the garden about 14m. Within the 14m we have a slope of about 80cm.

I was thinking of L-shaped stones and then filling up.

What is the cost-effective solution?

THANK YOU!!!! Regards

The thing with the planting stones sounds good!

Did you create a foundation from concrete there, or did you just place them on the ground?

We want to use the soil that is excavated from our house construction for the basement

Honestly, no idea.... When that was done, I was just with my wife in the delivery room... it was all over the place, whether with or without concrete.

But with us, no high loads need to be supported either... it's only just under 1m above the neighbor's garden level.

Perfect thanks for the picture!! The height difference would be similar here!

Does anyone know if a concrete foundation is needed here or not? Presumably one will be required...
