Container house - pros and cons? Your experiences are welcome

Hello and good day,
my husband and I are very interested in the container house concept. Does anyone have experience with it? How durable is such a house? Advantages and disadvantages? You can find quite a lot about it on the internet, but maybe someone can share something from their own experience.

Thank you very much

Best regards, Stella

The container house concept does not exist, so it probably sparks the discussion when you specify what you mean. Under such a name, concepts of modular houses have been discussed repeatedly for at least 100 years (young couple starts small, later a children's room is added, in the final expansion it becomes two-story with a conservatory, and so on); likewise, room modules in 40-foot containers or similar. Last year, someone in the forum mentioned a model from an Austrian provider who combines single- or two-story single-family houses from container modules, which are partially joined without interior walls. If I remember correctly, it was Combi-Box, but the forum search is not my friend today :-(
