The main goal in this transformation of a barn from 1822 was to integrate three flats with an entirely wooden structure while respecting the exigencies in terms of sound insulation and fire protection. In order to do this, the barn has been emptied and a wooden frame structure built directly against the planks to strengthen them and stabilize the barn. The planks have then been washed and treated to show their natural color and make it last in the future. On the south facade, an existing volume has been rehabilitated and transformed into a living room and an access has been created for the studio on the upper floor on the north facade. A particular care was given to the respect of the original barn in order not to damage its history and to respect the local rules for this kind of renovation (thinness of the roof, a minimum of new windows, respect of the existing volumes and materials...) The wood removed from the inside of the barn has been reused to create various inside and outside arrangements as furniture, doors and decoration elements.
