Technical schools don't do that (although it's a good idea!), but we have a unique project right now (also part of ArtMonument-MonumentArt): 9x24, an entire half-timbered house (abandoned after a fire in 2004), now rebuilt within the 9 days of the festival, 24 hours a day - only by volunteers. :-)

Since you're interested in these old buildings, I'd suggest you'd check my FB album with pictures of that rotten building (took them in April this year):
