In french : in "Les langages de la ville", Marseille, Parenthèses, 1997 (ed. B. Lamizet and P. Sanson) I wrote a paper named
"L'architecture de la place selon Camillo Sitte". In that text, I tried to explain how Sitte use an architectectural model (a room) to study an
urban one, and how he discovers by this way, a new relationship between architecture and town planning.
just have a look at Ernst Van de Ven`s space in Architecture and also E Schorske's Vienna end of a century (I am not sure about the title in English which I translated from Vienne fin de siecle ) the book was first written in English
