Table 2: Comparative Analysis-- Repair vs. Full Replacement

|---|---|---|
| Heritage Value | Maintains original character and increases residential or commercial property value. | Can decrease the architectural appeal and cheapen historical homes. |
| Environmental Impact | Highly sustainable; recycles existing materials and minimizes waste. | High carbon footprint; old wood ends up in land fills. |
| Life expectancy | Can last another 60-100 years with fundamental maintenance. | Modern units frequently need replacement after 20-25 years. |
| Energy Efficiency | Can attain substantial heat retention with draught-proofing. | Excellent thermal homes, but typically at the expense of visual appeals. |
| Preparation Permission | Typically not needed (unless in specific noted cases). | Frequently required in Conservation Areas; limited for Listed Buildings. |
