There are a number of preserving and restoration methods: frontal preservation, partial preservation, exterior restoration and interior preservation, or interior restoration and exterior preservation. Old buildings can have modern lighting and fire prevention equipment. Who says that old buildings have to be decrepit?
至於保存及翻新的技術和手法，那可多了：從立面保存、局部保存、外部修復內部保存，或內部修復外部保存等不一而足，老房子裡頭照樣可以有先進的照明或防火設備，誰說老屋一定要跟「殘破老舊」劃上等號？
