Hello!
I have a slope/hill on my property where I would like to "dig in" a relaxation room. What I'm very uncertain about is how to handle the roof since there will be a lot of fill, soil, and grass on top and not a floor level like in a "normal" basement.
Surely it's not as simple as casting a slab, building up three walls (the fourth wall will mostly be sliding doors), and then casting a roof and refilling so you only see the sliding doors in the hill?
Would you need a lot of waterproof layers, etc. (compared to the construction of so-called flat roofs)?
Are there alternatives to casting the roof?
I've been searching online but can't find much about this. I'm also considering making a root cellar next to the relaxation room. Perhaps one wall of the relaxation room can be used for this.
Does anyone have experience and some suggestions for a solution (if it's practically feasible...)?

You should probably have some form of waterproofing because concrete lets water through.
I would probably try with an aluminum roof that I would seal with silicone or something similar.
It doesn't matter how it looks as long as it becomes watertight.
Or simply apply plastic on top of the roof when it's finished, maybe with a little slope.

Interesting construction. It's certainly possible to pour concrete if you build a sturdy mold and everything, but I would probably look for Y-tong elements or something similar. The advantage is that they insulate much better and are lighter. Then I would really make sure to seal, but maybe not directly against the concrete. I would probably use isodrän panels on top of the concrete roof and on the outside of the walls. The walls need to be protected from moisture too, but it's very good if they breathe, and isodrän is excellent. Just on top of the roof, I would use two layers of isodrän with double layers of age-resistant plastic film in between. Alternatively, you could place some form of simple plastic/metal roof between the isodrän panels. The risk with that is that the metal might rust through long before the plastic film would. I would also make sure the roof has a slight slope so that the water runs away from the main building and outside the isodrän panels on the wall. If a drop of water gets through, it's no problem, it dries.
Then you will have a nice insulated relaxation room with walls that BREATHE. I assume you plan to tile or something, and then it's nice if it doesn't cost a fortune to heat because concrete conducts heat very well, second only to steel. Furthermore, the concrete construction with a diffusion-open exterior allows you to use a waterproofing membrane in the relaxation room but doesn't require one unless there's a risk of water from your relaxation room migrating into other spaces in the main building via the floor or walls. The water dries from the concrete both inward and outward, amazing.
