ᐅ Building a Living or Hobby Basement Underground – What to Consider?

Hello everyone,
We are currently planning our outdoor area and want to build a hobby room underground.
On top of it, there will be a layer of soil so grass and flowers can grow, as well as a garden shed that will be used as a sauna.
The room should be completely embedded in the ground and covered with soil.
The dimensions are planned to be 4x5 meters or 4x6 meters. Heating and electricity will be supplied from the main house, which is not a problem.
My question is what should be considered here. I want to build it myself and I am quite handy.
So I have some basic questions like:
Thickness of the base slab?
30 cm (12 inches) masonry with hollow concrete blocks, or other materials/thickness?
Waterproofing on all sides against cold and moisture?
How to build the ceiling?
Entrance maybe next to the sauna?
Light should come into the room through a wide window with a light well, or on the opposite side, underwater in the adjacent pond through a glass panel.
I hope you can provide information, help, and tips to make this project possible.
I have already looked online without success for similar projects but found nothing. Unfortunately, I only find information about underground cellars for storing fruits and vegetables.
Attached is an amateur sketch to illustrate the whole idea.
Best regards

If parts have to be done without EL, then of course it will be more.

A friend recently built a basement for 20,000 euros on a floor area of 80 sqm (860 sq ft). That works out to 250 euros per sqm (23 sq ft).First of all, that is an extremely low amount of money. He probably received little more than just the excavation and concrete.
Secondly, using a simple proportional calculation here doesn’t make sense. The 20,000 euros include things like the staircase, and the ratio of walls to floor area is significantly higher.

readytorumble3 Jan 2018 13:22You can expect to pay between 50,000 and 100,000 euros for a standard basement (not a livable basement). This, of course, always depends on local conditions (cost structure, soil, etc.) and naturally also on the size.
In my opinion, nowadays you won’t get a basement anywhere for 20,000 euros.

Well, I can only share what I have seen. For 20,000 euros, that included a complete basement with ceiling and all necessary work.
We received an offer from a local construction company for a complete house with 140 sqm (1,507 sq ft) of living space, fully basemented, for 150,000 euros.
So, I find some of the claims here about 100,000 euros just for a basement hard to imagine, sorry.
This is only about a 20 sqm (215 sq ft) room after all.
