Building a garden wall - materials and procedure?

Good evening everyone!

A while ago, I already complained about our unsatisfactory view into the neighboring garden where they put a metal shed on the border.
We are now pondering how to beautify our side of the garden so we don’t have to look at the shed for years.
My latest crazy idea: I would like to build some kind of wall ruin. I have a strong urge to do some masonry. The problem is: I have never done any masonry in my life.
I attached an example picture. (Ignore the window, I think I would leave that out).

What do you think, how difficult will something like this be? Can I just buy a few square meters of facing bricks from Röben and mortar and start building? Are there better/cheaper stones for that? I’d like it to look as rustic as possible. Unfortunately, eBay Classifieds isn’t offering anything right now – I’m also not a big collector, I’d always have to rent a car because nothing fits in my A1.

How would you anchor this into the ground? Can I just dig for a while (20cm?) and then place the first stone in the ground and build on top of it?
Or do I need concrete underneath?
Is this stormproof? How far would I have to set it back on my property (distance to the border) so that it doesn’t count as a fence? If it stays under 180cm in height, it shouldn’t need permission, right? (Sorry if these are again state-specific questions, just ignore them then).

Best regards,
the creatively inclined Kati

In principle: yes, there must be concrete underneath and a frost-free foundation should be made. We want to build a retaining wall with (imitation natural stones) stones. There are many products, e.g. EHL CITYANTIK-MAUER. You should then observe the manufacturer's specifications. For example, EHL specifies a maximum height of 0.98 m for a free-standing wall in wind zone 1.

If it should be higher, that would be easily possible with a gabion wall.

Thanks. I’ll have to google frost-free foundation first. Does it really have to be that meticulous? The wall is not supposed to carry anything, only some ivy should grow up on it.
I don’t want a clean look either, it should definitely be rustic, and the wall should not be straight or end on a level surface; the ruined look of the photo is visually desired. It should be planted lushly with greenery in front and then allowed to grow over in a country style.
That’s why gabions are not an option either; their style doesn’t fit our cottage garden wish.

There are such kits, that is quite expensive... theoretically old stones would actually work, but you've already mentioned the transport

:D

Frost-free means an excavation 80cm deep, then a concrete base (with gravel for a higher wall) If that weren’t the case, I would have already built one ;)

How far do I have to extend something like that onto my property (boundary distance) so that it is not considered a fence?

Just like it applies to trees in the Lower Saxony neighborhood law. As far as I know.

Thank you. I first have to google frost-free foundation. Does it really have to be that meticulous?

Not necessarily as meticulous as Google suggests. The problem is that after several winters, the wall could simply collapse because the ground becomes damp and frost could cause corresponding damage. For our wall, which is about 10 meters long, it took 3 people a weekend. We got a concrete mixer from the neighbor and cement came along with the stones. Then two small trailer loads of gravel and off we went.

The ruin look of the photo is visually desired. It should be lushly planted in front and then grow over in a country style.

There are sets. For example, google "EHL Antikmur Ruine."
At our hardware stores, there are also very often individual rustic stones, which are still reasonable in price. For example, "iBrixx" is the house brand of Hornbach.

So meticulous as Google claims, not necessarily.

I don't know what Google claims, but for a 150 cm wall and larger (and not knee-high) I would adhere to the frost-free 80 cm footing. Otherwise, they could topple quickly.
