Can a covered terrace be counted as living space?

Is this, as mentioned at the beginning, really an excerpt from the HE-HBO of 2006 (or perhaps a commentary)?

I read post #42 as if the quote were taken from a comment (unfortunately not mentioned where and by whom). Doesn't Google help you with the text snippet search?

I had already tried the text search. Without any useful result. Hopefully, I didn't search too "carelessly".
