Yes -- until about 1970, houses in the UK were built with a
life expectancy of about 200 years. From that point, a wide
diversity of construction changes has appeared, which is
likely to lead to a number of shorter lived houses. As a
surveyor pointed out to me, this isn't something the public
have taken on board yet when considering the value of a
property, which means many houses are built using cheaper
shorter life materials in the knowledge they will still
sell for the full price.

Interestingly, offices are usually built with a 30 year
life expectancy.
