For the purpose of this debate, strict preservation of historical architecture means that architectural heritage should be safeguarded at all costs, emphasizing the need to retain the authenticity and historical significance of structures. It is the belief that in preserving architectural heritage, no alteration can be made that will change how the building look like, this means using the same material, retaining the same shape, etc.
Repurposing and redesigning historical buildings involves giving them new purposes and modifying their design to suit modern needs.
