Gentrification is the process/movement of more-affluent individuals into areas/neighborhoods of lower-class. This process occurs globally and at many scales, some of the more notable cases are iconic neighborhoods like Haight-Ashbury in San Francisco and the Lower East Side in New York.

The reason I bring this up is because I have visually witnessed a neighborhood go through this exact process over the past 6 months (I suppose I am personally contributing to the process). Regardless of how many case studies you see or how many articles you read, you can’t understand the local impact until you see it first hand. In the past 3 months I have seen residents chant “stop gentrification” at random pedestrians, witness a guy get off the subway and yell at the passing crowd of people, “where did all you f’ing people come from? It didn’t use to be like this,” as well as various forms of street scripture in the same spirit.
These communities are often first infiltrated by artist who are initially attracted to these “found” neighborhoods because of their cheap rent and the patina-like qualities. These artists often create an unintentional ripple effect on the neighborhood, and although their intentions are completely harmless, they often generate a “hip” factor. This hip factor is not usually enough to convince people to live in these communities, but they start gravitate towards them for entertainment and art. As businesses and bars start to capitalize on this transformation, the neighborhoods become more and more appealing to the masses. It is at this point where the lower-class residents are forced out and new money is invested in development, safety, and infrastructure.
Gentrification is just one of the many ethical issues that keeps me up at night as a designer/architect. Although I realize that nothing in life is static and that gentrification has many positive benefits on the current and future population of the community, I can’t help but think about the layers of culture and history that are replaced by such temporary, sterile infill.
