So based on the previous posts, I assume that the creator has no idea about earthworks done by oneself. And then I would also definitely leave it alone because everything is based on that. A layperson cannot carry that out properly, especially without the guidance of an expert!

Saving money is fine, but then better do the own work elsewhere. Laying tiles? Doing drywall yourself? These are all things I can fix in 10 years if there are any defects.

Um, no idea if you can also get gravel and cement for free, but for me the calculation (roughly) looks a bit different:
10x10 m is unrealistic because you still need working space around the house, so rather 13x13 m.
That would be about 50 running meters, 1.7 m high and the assumed 0.2 m thick, making 17 m³ of concrete.
Dense concrete approx. 2500 kg/m³
With mixing ratio about 1:4 you need 500 kg cement, i.e. 20 bags.
I haven’t found any below 2.- € per bag yet (but grateful for tips).
Just the cement part costs about 40.-
Gravel (need 2000 kg) costs about 30.- € per ton for us, i.e. 60.- €/m³. So we are already at 100.- €/m³ (self-mixed) without water, electricity, and labor.
A steel reinforcement mesh 2 x 6 m also costs about 50.- and you need several.
Apart from the fact that you can’t mix this amount all at once and the concrete wouldn’t be homogeneous, there is the question of how you want to secure the entire wall from falling over?
Dig a deeper trench and anchor the wall underground or pour an "L" shape, which requires even more work and concrete?
For that money, you can slope with RCL very gently, even with natural gravel you have less than 45°.
I myself also have a natural stone wall of similar height, which I catch behind with concrete as self-poured L-beams in 1 m pieces.
However, these are not 10 m and do not have to hold a house.
Don’t take it the wrong way and it’s not meant badly, but I think this recommendation is madness!

: Filling is truly not rocket science, you just have to make sure the ground is load-bearing and then fill and compact cleanly in layers of 15-20 cm. It takes time, better to run over it twice as much, then it will also be firm. How it works with RCL I don’t know, but natural gravel definitely has to be a bit moist when compacting!

Hello Peanuts

My idea doesn't have to be the best. It's one of several to help the 305. I've had bad experiences with plastering and prefer to work with concrete. But you're right, not the best for a layman.

Why have you had bad experiences with Abböschen? For me, even Abböschungen steeper than 45° have held up for two years without (feelingly) a single stone moving. With the frog it’s just a crappy job, but I think 25 degrees can be made well and above all, the space is already backfilled then. Depending on how well you can get from all sides, you can also generously spread gravel/RCL where the house is supposed to stand and surrounding fill sand and then compact, then the angle is even flatter. If a shovel of sand gets mixed into the gravel, that won’t make the house collapse, but it’s much easier to work with. BTW, I also quite enjoy working with concrete, only in those quantities it’s barely doable and above all, I don’t see how a wall 20cm thick is supposed to hold if tons of earth are backfilled and compacted behind it. And how do you get the gravel into the “Schüssel” if it’s closed all around? Shoveling it over the wall? Heavy vibrating plates, rollers, etc. you can hardly get in and out either...

Hi, attached is our cost plan that we received from our construction company. The house itself has increased to €251,000 after the selection process.

You can easily postpone and tackle all the garden work after moving in, when there is money in your pockets again. That's what we'll do too. The same goes for paving work. In the meantime, we'll just stand on the gravel.

You might also be able to scale back a bit during the [Bemusterung], depending on what you have chosen.
