What do you call this? Architecture that transforms and is being transformed? In colonialism, architecture plays a role in transforming the colonized society. The built environment has a large impact on how we work, live, and play. At a micro-level, the modern detached house is closely tied to the idea of the 'nuclear family.' Many cultures are not compatible with this idea. In this case, architecture is transformative.
Society impacts architecture. Changing values, fears and demographics all impact the design and function of the built environment. If the demographics or economic level changes, so does the built environment, such as gentrification.
I am not sure if this is analogous, but it is a unique relationship between society and the built form. This is why I am trying to find the right term for something that transforms at the same time being transformed.
Based on your digression, the architecture is impacted by trends that could have negative impacts. I think it is inevitable that people will eventually treat the French Provincial as the norm and part of the fabric. One thing I learned is that most people can not tell the difference between good and cheap wine. Those who can are few.
