Here post-WW2 "veteran houses" are often popular targets for renovation, particularly if they're made of logs. '60s/70s is seen a dark age of homebuilding, with all kinds of new fancy designs and materials which proved to be rather unsuitable for our climate, or probably any climate. (For example, it was very fashionable to have flat roofs - great idea in a country where 1 metre of snowfall over winter is commonplace). Things improved in the '80s.
Apartment blocks built over the last ~10 years tend to be horrible, mushroom projects propelled by housing bubble, with awful layouts designed to maximize number of apartments which can be sold. With the end result that they don't sell because they're cramped, dark and generally suck. Also, often put together by outsourced small companies who made the lowest bid due to use of untrained cheap foreign labour.
