Comment on 3D printing a house

What do you mean switching? Think this is more about using less concrete than stopping to use it entirely. That also helps, but yea it’s a problem.

Most houses around these parts are made of wood, not concrete.
In Denmark it’s usually bricks or other stone like materials or concrete. Never understood why there is this difference across the world in how houses are usually built, but wood seems a very… Temporary material for something like a house? I’ve lived in buildings from the 1910s, I can’t imagine anything made of wood lasting that long.
If they’re taken care of properly they can last centuries

My house is wood and was built in 1923.
Houses are made of wood in the US because we didn’t chop down our forests in the 1500s. European houses generally fall into the category of 1000+ year old stone or modern brick
