Le Guern House, Morbihan

Written by Herbert Gruber

A building with round walls constructed using the Gagné technique (mortared strawbale – straw bales in a cement grid) and a wooden post and beam construction. Even though it is no longer built this way today because of the many thermal bridges, this almost historic building is an example of the diversity of straw bale construction techniques.

More about this Straw Bale House

A building with round walls constructed using the Gagné technique (mortared strawbale – straw bales in a cement grid) and a wooden post and beam construction. Even though it is no longer built this way today because of the many thermal bridges, this almost historic building is an example of the diversity of straw bale construction techniques. And what is particularly interesting here is the construction detached from the (load-bearing straw bale walls, with which one can easily have such load-bearing buildings statically calculated and approved.
