This was really neat and impressive and doesn't look as complicated as I imagined. I was also thinking of laying some cement pipes with a diameter of 160-180 cm, but they seem to cost about 4000 per meter of pipe (maybe because I live in Norway) and are not as nice. Due to the tight space between the properties and the neighbor planning to build a granite wall on her side of the border this fall, I need to have my root cellar ready in a month if there’s going to be one; otherwise, I’ll undermine her wall when I dig, so it's just a matter of getting started. I'm not entirely decided but will post a picture if it happens. How did you handle drainage and groundwork under the first layer of blocks?

How did you manage with drainage and groundwork under the first layer of blocks?
It wasn't as complicated as I first thought. Underneath, there's some macadam and geotextile fabric with sand/gravel for leveling. I haven't poured any footing, but I hope and believe the ground is stable enough anyway, it's a very sandy plot... Go ahead and post pictures
Today I thought I'd go and buy lecablock and get started after the weekend. The one you built looks just the right height in the pictures, but when I compared the drawing you posted first with the pictures, it seems like you only have four layers of stones, compared to 6 layers in the drawing and you've written that you laid 5 layers high. Is that because one layer is underground? It also looks like the stones in the picture are slightly taller than wide, so you might have other dimensions. What dimensions did you have for the stones and what was the final ceiling height? I've posted a picture here of the place where I plan to build it. It's tight between the houses, and our plot is only 2 meters wide there. But the construction company has, fortunately in this case, put too little mass next to the house so there won't be that much digging for me. A bit of coarse gravel on top and some kind of stone-and-clay masses underneath. I'll post more when/if I get started 
I bought the stones from byggmax, 19x19, maybe it's the joints that make them look taller than wide. The arch is 9x19 then. The internal ceiling height at the highest point is about 1.25m. I also laid slabs as a floor that built 5cm. That's right, it ended up being 4 rows of stone before the arch. I had a hard time estimating how high the construction could be without it getting too high before we started.

Thank you for the good response. It has been slow progress for me, but at least it's moving forward. After your answer, I bought lecablock of the same dimension as you (note the fox in the background of the picture). I live in Norway but am less than an hour to Strömstad, so I bought there because it was less than half the price in Sweden.
It took some time to dig out by hand in all the clay and gravel, especially since both clay and gravel want about a 45-degree angle to prevent collapsing. After that, I have laid gravel, landscaping fabric, and gravel again, and finally started to build. I had a lot of rebar, so I reinforced each layer. Now four layers are done, so next week I will start with the arch. To be continued

How are you planning to handle it between the root cellar and the house?
