It has little to do with an old, proven half-timbered house. It is more of a look-alike.
No house lasts forever. Much depends on regular maintenance. Many things are also no longer up to date. Just the tiny windows in the old houses.
Who knows what will happen to our houses. In 30 years the bathrooms will be due, in 50 years everything will be overhauled. Floor coverings, electrical systems, plumbing, walls, etc. In 80 years damage will come to light because the renovation work in recent decades was sloppy.
