In 2020 there was a fire at the Guga S'thebe Cultural Center Theatre building in Langa, Cape Town. The theatre had been designed and built by German architecture students from the University of Duesseldorf in collaboration with Carin Smuts of CS Studio.
With a large oversailing timber structure and metal roof covering, the walls were built from stacked containers that were insulated with 100mm thick pre-fabricated light clay straw panels, which were clad externally with 2nd hand fruit pallet boards, lapped vertically.
While the fire destroyed over half the roof, despite the intensity of the blaze, only the tops of the timber-clad light clay panel walling were damaged, as due to the excellent heat resistance they simply charred and actually helped stop the blaze from spreading giving time for the firefighters to do their work.
In 2021 Grinker Contractors were contracted to replace the roof and Eco Design was engaged as specialist sub-contractors to re-make and replace all the damaged light clay straw panels.
Led by Andy Horn of Eco Design and with the assistance of his team as well as Clint Abrahams of the UCT school of architecture and some volunteer students, together with some labour employed from the local area, the frames were remade and light clay straw panels were re-manufactured. Then once the panels had had time to cure, the panels were erected and the odd gap plugged with a mix of light clay straw.
This project was a great learning experience and provided insight into a way of pre-manufacturing light clay straw walling on-site. This has the advantage of providing a means of working in more controlled and worker-friendly conditions while dealing with the issue of shrinkage that one has with this technology prior to their being built-in on-site.
Technology-wise, this is an interesting space to watch and you can be sure that other work will follow from this experience.
