CAT Materials Week

One of the best modules of the course at the Centre for Alternative Technology (CAT) was the materials week. We got a chance to explore a range of different alternative construction techniques and materials. As well as the materials shown in the gallery (hempcrete,  earth, and lime) we also learnt about building with straw bales and timber.
