Following the closure of the Marylebone Police Station, Westminster County Council gave permission for the existing building at 1–9 Seymour Street to be demolished and for a brand-new development to take place. Within this ambitious £60 million project, the developers wanted to construct a seven-storey mixed use building, including a two-level basement, residential block, restaurant, retail space, commercial office block and school.
Working with Galliford Try and Delta Membrane Systems, we knew that a basement waterproofing project like this would require a pragmatic approach. Tim Herbert, our managing director and CSSW qualified structural waterproofing surveyor, was involved at the design phase to provide his expertise from the start, ensuring the basement would be designed correctly to prevent any water ingress.
