GRAND RAPIDS — Leaders of The Diatribe Inc. are planning a mixed-use building that would house the nonprofit’s offices as well as retail storefronts, apartment units, and a performing arts venue. The nonprofit, which uses performing arts to empower young people to share their stories and raise awareness of social issues, has signed an option and purchase agreement for an 18,338-square-foot building at 2040 S. Division Ave. The Diatribe works with about 5,000 students a year across 20 to 30 schools. PURE Architects is designing the project, which calls for a full renovation of the building. Plans include creating offices for The Diatribe staff, programming space on the main floor for about 30 students at a time, a venue in the basement where students and artists can perform, two retail storefronts for local Black and brown entrepreneurs, as well as eight apartment units to house creatives.
