I'm trying to find the English translation for the Dutch word 'welstandsgebied', which roughly translates to something like 'wealth zone' in the context of land use control by municipalities.
A 'wealth zone' is an area that is controlled by a municipality (which issues building permits) to ensure that architectural cohesion is maintained on a predefined level. To my knowledge, nearly all built-up areas in the Netherlands are part of such a zone.
What is the proper English word or expression for this?
