I am working on the Golden number and I know that, in Montpellier (F 34000), Ricardo Bofill designed the "place du nombre d'or" using this concept. However, I still do not find detailed explanations on how and where he used this number which is often the ratio between two lengths, or which is translated into a special geometry of pentagons.
If anybody can help me in finding comments from the author or any publication on the topis, I would greatly appreciate.

I send a mail to Bofill's office, bur I do I have few chances to get an answer...
