Résumé en anglais
There are three principles in the maintenance and revitalizing of traditional architecture: 1) The scientific restoration by conservationists, which is an exceptional and expensive way. 2) The adaptation of modern building methods. This means unnecessary replacing and renewing of almost all old structures, which means wasting of historic values and spending of money. 3) The traditional method - to restore a house in the same way as it was built. Traditional materials and skills are needed.
