Honestly wouldn't normally narrow it down that much in Norway either, although most red buildings are barns and not houses. "The lake" is not a problem in Norway, most towns are in a glacier-carved valley with exactly one lake. There are small lakes in the mountains, but not in places which would usually receive mail. In this case, there just weren't a lot of houses right next to the lake for whatever reason.

This is the case in rural France as well. They have lieux dits, (named places) that are the name of a house or a conglomerate of houses.

However this isn't compatible with the online ordering/delivery economy, the postmen might know all lieux dits, and their inhabitants , but a delivery driver might not know. Therefore street names and house numbers are being assigned.
