1, safety first
Ancient buildings have a history of more than 100 years, and the components have to undergo different degrees of weathering or flashing. When finalizing the case, whether the building is safe or not should be regarded as one of the principles of repair.
Step 2 unify the style
The repaired parts should be as consistent as possible with the original style. Respect the original style and craftsmanship of ancient buildings and maintain historical features.
3, prevention first
Repair should focus on prevention, and ancient buildings should be regularly maintained to eliminate accumulated diseases and hidden dangers in the bud.
4. Utilization of old materials
Using old materials can not only save a lot of money. From the perspective of building materials, it can also retain the characteristics of the original building.
The biggest difficulty in the restoration of ancient buildings
The difficulty in the restoration of cultural relics lies in the systematic and comprehensive cognition and research on the value of cultural relics. The restoration of cultural relics can't "treat the symptoms only", but should protect these real historical information and values as much as possible based on the understanding of the overall value of cultural relics, so as to keep the building in a relatively healthy state. The complexity of the transformation of cultural relics buildings far exceeds that of ordinary buildings.
In the principle of cultural relics repair, the original part of the cultural relics building should be preserved as far as possible, and the cultural relics building should not be disturbed or changed as far as possible. Any repair is actually a change. The more cultural relics are restored, the better, but the less changes, the better.
We should try to avoid change, and the smaller the change, the better. We should keep as many parts as possible that can reflect artistic value, historical value or cultural value, and try to leave all these things behind.
