|---|---|---|
| Heritage Value | Preserves initial character and increases residential or commercial property value. | Can decrease the architectural appeal and devalue historic homes. |
| Environmental Impact | Extremely sustainable; reuses existing materials and reduces waste. | High carbon footprint; old timber ends up in land fills. |
| Life expectancy | Can last another 60-100 years with standard upkeep. | Modern units typically require replacement after 20-25 years. |
| Energy Efficiency | Can achieve substantial heat retention with draught-proofing. | Outstanding thermal residential or commercial properties, but often at the cost of aesthetics. |
| Planning Permission | Usually not required (unless in specific noted cases). | Typically needed in Conservation Areas; limited for Listed Buildings. |
