I used John Darbelnet's Pensée et Structure when studying French at Purdue University in the late 60s and early 70s. He did not offer a "faire" construction at all. There were four choices:
Ce bâtiment a une longueur de trente mètres.
Ce bâtiment a trente mètres de longueur.
Ce bâtiment a trente mètres de long.
Ce bâtiment est long de trente mètres.'
It's things like this that make me question the quality of this site. John Darbelnet was a distinguished pedagogue but of a different era. I would be interested in further input. La grande robert has been of no help.
