This may be too late to add for your consideration.
There was a participatory architectural project completed by Ralph Erskine
et al in the 70's in Newcastle, UK.
It was a very large slum clearance project now referred to as the Byker
Wall, (title probably influenced by the local Hadrian's Wall). During
early demolition, before the actual building project was started, an
on-site design office and citizen's center was opened, also a transitional
news magazine was started called "The Phoenix", all to handle local
people's questions, concerns, and ideas. I believe that saving local
artifacts and incorporating them into the new designed environment was one
of the citizen motivated changes.
All of the above key words are Googleable (?) and as far as I know a few of
the original transferees/ occupants in the project are still around for
interviewing. (Although you would probably need a Geordie translator)
