The architect suggest to add shutters for the summertime confort but this option is not yet accepted by the owner. The building is located at 627m altitude

b) Acoustic comfort is achieved trough the realisation of efficient double glazing. The roof insulation and walls will be performing in acoustic at thermal level.

Building materials
The use of wood is present in the project (mixed structure wood, metal, concrete): dressing of wooden ceiling, some walls are wood frame, wood siding is used on interior walls.
The insulation of the walls and the roof is made with cellulose wadding.
The roofing will be made of zinc.

Test of special methods
The llauze is used for roofing external dependencies, several stone walls have been preserved for heritage project quality.

The building is located near a cliff near a river and a diagnosis is required in building permits authorized. The project is located on a site classified as historical monuments there are two medieval towers on the site. The projet is located near an old processing factoring fluorite
