 Infilling can be a way to repurpose largely unused urban areas, and while some may hear infilling and think of the term gentrification, which can carry a negative connotation, Lupton says focusing on a community need can create a distinction. When there's a really serious emphasis on affordable housing and on making it such that people can afford to live there, that I think that, to my view, it's not gentrification, or either that or gentrification is not a dirty word, that you're creating more opportunities than you're taking away.
