What did they build more of then?

They built at least one house. That's more housing.

So they did not in fact build more, by any definition that a reasonable person would use.

		OK so the "at least one" is a Binface campaign promise, used as a joke here. I'm going to leave it up to you to figure out if the Netherlands builds more than 1 additional housing unit every year.
