In the tropical Vietnamese province of Dong Nai, Southeast Asian architecture firm T3 Architects has completed the Hippo Farm Bioclimatic Dormitories, a cost-effective housing structure that uses locally sourced materials and bioclimatic design principles to stay naturally cool and comfortable year-round. A limited budget and a brief that specified low-impact construction led the architects to explore traditional construction methods such as using Vietnamese bulk rice husk with inspect-resistant diatomaceous earth for the roof insulation.
