An upcoming community center in Tanzania will be defined by its cutting-edge 3D-printed design. However, rather than being built from layered concrete as you'd usually expect with 3D-printed projects, its walls will be created using locally sourced soil.
The community center is being headed by Hassell, in collaboration with Australian-based charity foundation One Heart, for the Hope Village in Tanzania. It forms part of a wider plan to provide housing, a school, childcare and skills training to vulnerable young girls in Kibaha, eastern Tanzania.
"The Hope Village community hall design seeks to create a beautiful, functional, safe and uplifting environment that provides both hope and education for vulnerable girls," says Mark Loughnan, Principal and Head of Design at Hassell. "The hall is a welcoming space that creates an innovative central activity hub that also connects with its surrounding environment. The design and building process for the hall aims to engage the community and provide ongoing opportunities for local participation and education throughout construction."
Structurally, the community center is quite complex. Its walls (which are not load-bearing) will be built using soil sourced within 25 km (15.5 miles) of the site and a WASP 3D printer. WASP has been researching this stuff for years now and a previous project used a mixture of mud, straw, rice husk and lime. A similar process will be happening here, with a clay based earthen mixture being extruded out of a nozzle in layers to build up the walls. A representative at Hassell told us that the walls will also be reinforced with a thin wire mesh between layers.

Inside, the design brief calls for a large, open floorplan that suits the local climate, with a limited number of columns to ensure its flexibility. To achieve this, Hassell has conceived a central steel beam that serves as the structural spine of the hall. This will support a roof made from locally sourced timber sections. The roof will feature cladding made of readily available corrugated metal sheet panels, helping to keep costs down.
The project also involves the Institute for Advanced Architecture of Catalonia, IAAC, and ClarkeHopkinsClarke. We've no word yet on when it's expected to be completed, though prototype walls have already been produced.
