We also used traditional technique of seismic resistant construction with timber-only design for schools which has a wooden frame inside stone masonry envelope called nang che. In 2015, the timber frame prevented the complete collapse of a building in Shya La in Nubri even though the outer stone walls fell down.
Since the classrooms also had to be acoustically sealed, in the Bihi school we filled the gap between wooden wall panels with sawdust to reduce noise, and also insulate the rooms from the cold.
By using local materials we were not just preserving traditional architecture, village artisans and carpenters also got jobs, and nearly forgotten building techniques were revived.
Interns from my universities in Germany and Spain have travelled to Tsum and Nubri to see for themselves what we built, and learnt about local Nepali culture as well as the reconstruction process.
Despite obstacles we have now handed over the schools and health post buildings in Bihi and Chumling to local communities.
