2.1 From whitewashed cob to silicatization
Restoration work only concerns masonry, and excludes other facade components such as doors, windows, balconies, roof undersides, etc.
At the time, air pollution was non-existent and thermal differences between the outside and the poorly heated inside were minimal. Materials suffered less than they do today.
