A "former building" refers to a structure that has been abandoned, repurposed, or demolished. These buildings may have historical significance or architectural value, often reflecting the style and culture of the time they were constructed. Examples include old factories, schools, or homes that are no longer in use. Many former buildings are preserved as landmarks or converted into new spaces, such as museums or apartments. The process of repurposing can help revitalize neighborhoods and maintain the history of a community. Cities often have regulations to protect these structures, ensuring that their legacy is not lost.
