The farmer's Aggregation Centers were built in support of Bangladeshi host communities affected by the Rohingya refugee crisis. Each Aggregation Center brings together 300 smallholder women farmers to strengthen their market stability and supply fresh produce to the refugee camps. Designed through extensive collaboration between farmers, architects, and humanitarian actors, a new typology of Aggregation Center was imagined to serve as a community space. The center enables robust livelihoods clusters to gather and process, store, and sell produce while also providing a test kitchen, shop front, meeting area, and room for childcare. Through participatory construction workshops, the center was built by the community using locally-sourced bamboo, brick, and earth blocks compressed on site.
