Hi,
my wife and I have bought a plot with an existing property. After completing many tasks inside the house, we now want to improve the garden.

The plot borders a field, but it is about 1m (3 feet) higher than the field behind it.
Cross-section looks roughly like this: on the left is the field, and at the top right is our garden.

Between the retaining wall and our garden, there is a small slope currently overgrown with weeds. This means we have to do a lot of maintenance, and we would like to change that.

One idea was to build a wall there with landscaping stones and simply extend the lawn. Grass is easier to mow than nettles, and we could also plant bee-friendly plants in the landscaping stones.

I had a long discussion with my father-in-law about how to build this wall. He is very experienced in DIY work, while I am not. I have watched several online guides on how to build such a wall.

The guides all recommend building a foundation. My father-in-law says this is not necessary because the soil there is established topsoil (in place since at least 1960). He also said it would be a lot of work.

I’m still unsure. A friend advised us to keep some distance from the wall on the left. The father-in-law says this doesn’t make sense because otherwise, the foundation you would build (version on the right) wouldn’t hold.

What do you think?
Foundation, yes or no? Is it necessary if the soil is settled topsoil, the wall is backfilled, and I can lean it with a slight slope?

Cheers,

No foundation, yet it holds.

Thanks for the feedback. How long has your wall been standing?

In 2017, the bottom layer consists of concrete, followed by pebbles, with the top two layers being fully soil.
