Thanks for your winderful post. This is Matt Nohn whi has led the concept for the Bank's new core housing program in Indonesia, collaboratively with many others. I am in Chennai at present and would love to visit some of the sites. Is your study available by now or are you able to provide other information on the findings and site locations? The link in the blog does not work...
PS: for everyone following the incremental housing idea, this training may be interesting: https://app.box.com/s/wg06zweqpcb5gw2lkawwv81ok351lwam
