Facade retention is a common practice in construction and renovation projects where the original exterior of a building is preserved while the interior is completely gutted and renovated. This technique allows developers to maintain the historical or architectural significance of a building while still meeting modern building codes and standards.
There are a few different methods of facade retention, including installing structural steel frames to support the existing facade during construction, using tie-back systems to stabilize the facade, or creating a new structural system within the existing facade. The method chosen typically depends on the condition of the existing facade and the requirements of the new construction.
Facade retention is often used when renovating historical buildings, as it allows developers to preserve the original character of the structure while updating the interior to meet current needs. It is also commonly used in dense urban areas where space is limited, as it eliminates the need to completely demolish and rebuild a structure.
While facade retention can be more expensive and time-consuming than traditional demolition and reconstruction methods, it is often worth the investment in order to preserve the cultural and historical significance of a building. Overall, facade retention is a valuable technique that allows for the renewal and modernization of existing structures while maintaining their original charm.
