  • Project Status: Complete
  • Location: London
  • Client: EC Harris


This project involved the strip out of a 7 storey grade II listed building and the strip out and demolition of a 9 storey 1970s built office block within its central courtyard. Working in close collaboration with the Client, EC Harris, we developed a comprehensive and technically capable demolition strategy which was a requisite because of the constrained urban nature of the site.

In addition to this, Heritage surveys and temporary works design were conducted prior to commencement of works. There was a substantial Listed Building consultation as the building itself is a Listed Structure and the site lies within a densely populated district in Central London administered by the Corporation of London.

Works included the removal of large quantities of Asbestos Containing Materials (ACMs), careful demolition of selected elements within the building, with all arisings being taken off site for disposal/recycling at our licensed facilities.

Key Elements

  • Isolate/disconnect all services
  • Erect all hoarding
  • Fully scaffold the office block
  • Remove all asbestos
  • Strip out building
  • Working within Listed Building
  • Liaison with the Corporation of London


  • Complex nature of the structural elements.
  • Risk of premature collapse as building is demolished.
  • With only one usable access point available to us, delivering
  • machinery and removing demolition arisings had to be carefully choreographed to ensure vehicle and pedestrian traffic at the front and sides of the site were not disrupted.
  • Highly restricted site access / egress

How we made a difference

Working collaboratively with PGCS, our in-house structural engineers, we produced demolition methods statements and solutions which made allowances for the 1970s structure having been built against a 7 storey Listed Building.
