My Google-fu has failed me.

I've tried rewording the query, but I can't come up with an answer. I need to the know the height of a standard Haussmann building in Paris. It can be on the Champs Elysees or the Boulevard de la Madeleine. I know the heights were standardized, but all of the references I get are tourist ones telling me that the height was standardized -- not what the standard is. I'll take meters and would prefer feet. (I can tell they're about seven stories, but the stories are irregular. Also, as I know from my own time in a 19th century apartment, a story is closer to 18' than the more modern 12' for residential.)

Surprisingly, the other question I needed to know the answer to was much easier to find. The Champs Elysees is 229 feet wide; the Grands Boulevards are 45 feet wide.
