Project case study
Salisbury Square
Independent waterproofing design for the City of London Corporation's new courts development at Salisbury Square, with Avison Young as project manager.
Salisbury Square is the City of London Corporation’s new courts development, a public-sector scheme on a constrained City plot with the operational, security and long-life requirements that follow from a judicial building. CLW was appointed as the independent waterproofing designer, working under Avison Young as project manager.
The performance brief was uncompromising: BS 8102:2022 Grade 3, sustained over an institutional design life, on a basement structure that has to host court operations rather than commercial fit-out. Risk assessment, design philosophy and specification were developed to that standard from first principles rather than carried over from a comparable commercial scheme.
The value of independence on a public-sector courts development is straightforward, the waterproofing decision has to be defensible against scrutiny that long outlasts the construction programme, and the design rationale needs to read as the work of one specialist rather than a sequence of compromises.
