Beyonc, Tina Knowles and Kelly Rowland attended a ribbon-cutting ceremony on Tuesday for the Knowles-Rowland House in Houston.

The project transforms the former Knowles-Rowland Center for Youth into permanent supportive housing for people who have experienced chronic homelessness.

According to the U.S. Department of Housing and Urban Development, chronic homelessness generally refers to someone who has been continuously homeless for at least one year or has experienced at least four episodes of homelessness over the past three years totaling at least 12 months.
