Structural Appraisal of London House, St John's Wood

The appraisal confirmed that London House retains a robust reinforced concrete framed structure typical of post-war residential construction, with reinforced concrete floors, columns and shear walls providing the primary load-bearing and stability systems. No evidence of significant structural distress or movement affecting the overall integrity of the building was identified during the visual inspection. However, the assessment highlighted that the absence of original structural drawings means assumptions regarding transfer structures, reinforcement details and robustness require verification through targeted investigations. The report also identified the cumulative effect of decades of balcony alterations, façade modifications and rooftop additions, together with the need to consider long-term durability of exposed reinforced concrete elements and the potential impact of surface water flooding on the basement and lower levels.
