These two videos demonstrate the vast differences you can get in an underground home, personally I prefer the more rustic home, I don’t think I would ever be comfortable in a modern structure, they are too sterile and cold for me, but each person has ideas about how they wish to live.
This first video shows a very rustic hobbit style underground home, in fact you can’t stand upright inside the main space, I would want to be able to stand up, but wouldn’t require extra headroom besides that.

The second video here showcases more modern underground homes, enjoy!

What do you think? Would you live underground? Would you prefer rustic or modern?
