What property does the term 'Brownfield' refer to in architectural projects?

The term 'Brownfield' specifically refers to a previously developed site, particularly one that was used for industrial purposes, which may have been contaminated by hazardous substances or pollutants. These sites are often characterized by the potential for environmental cleanup, making them viable for redevelopment.

In architectural and urban planning contexts, addressing brownfield sites is critical because repurposing these locations can revitalize neighborhoods, reduce urban sprawl, and minimize the environmental impact associated with developing greenfield sites—those that are undeveloped and often located in natural areas. By transforming brownfields into productive spaces, communities can benefit from economic development while also considering environmental sustainability and public health.
