Reusing Existing Buildings

This month we will discuss the structural reuse of existing buildings in the UK. The United Kingdom has a rich historical and architectural heritage. Reuse is an effective strategy for reusing an existing building for the purpose other than what it was originally designed for. 

This approach offers many advantages including sustainability benefits, urban regeneration, cost-effectiveness, potential to add property value and extended use of the building.  

There are many challenges with existing buildings and not all buildings will meet the criteria for reuse. Items to consider normally include structural integrity, compliance with current building regulations, and financial costs. 

The Importance of Structural Rescue: 

1. Preservation of Heritage – Many buildings in the UK hold significant historical, cultural, and architectural value. Preserving these structures is essential in maintaining the country’s historical narrative and cultural identity. 
2. Sustainable Development – Repurposing and rehabilitating existing buildings is often more sustainable than demolishing and constructing new ones. It reduces waste, conserves resources, and minimizes environmental impact. 

The structural reuse of an existing building requires the following: 

• Initial planning and investigations – This is crucial as the completed building must serve the need of the market and the current building regulations. This stage normally involves the architect looking at various feasibility options. The history of the building should be understood in terms of use and if possible, requesting any historical drawings or archive information. A visual non-intrusive inspection of the structure as the first commencement point is always worthwhile. There may have been previous alterations to the building. 
• Engineering expertise – This will be required for assessing existing buildings in relation to safety and durability. Over time, buildings may suffer from structural weaknesses due to age, environmental factors, or poor maintenance. Ensuring these buildings are safe for reuse and occupancy is crucial. For the structure it is worth undertaking targeted investigation works and testing of the existing material properties. In some cases, a full strip out may be required to make a full assessment on top of undertaking a full structural analysis to assess load paths and 3D scanning.  

We have had recent projects where stabilisation is required in the form of temporary works.  Also, other repair and reinforcement methods have been adopted by LSY in the form of the following: 

1. Repointing – Replacing deteriorated mortar in masonry construction. 
2. Crack Stitching – Using stainless steel rods to stabilize cracks in walls. 
3. Structural – Adding steel beams or columns to support weakened areas.
