Depends on the country. A well-built and properly maintained house in Germany can have a service life of 80 to 100 years or more. Some may even exceed this range, especially those that are regularly updated and renovated.

A well built and properly maintained anything can last hundreds of years. Proper maintenance likely involves heavy replacement of parts, mind. And is very contingent on no damage.
I will add I just moved out of a hundred year old house in Seattle. I know they can happen. I also know that house had no air conditioning and retrofitting one on would have basically meant a new house. Even if it looked the same.
