St. Pancras Chambers Clock Tower

A slim cantilevered steelwork mezzanine floor has been installed in the famous Grade I* listed building in St. Pancras. 

An infra-red survey was undertaken to identify flue positons to work out which parts of the walls could be fixed to.  The limited availability of fixing points meant a cantilevered solution was required.

To keep the floor structure very thin the structure was pre-tensioned prior to elements being fixed in position. To achieve this a detailed sequence of installation was prepared for which calculations were prepared to reflect each of the respective stages.  The key to this design was controlling deflections.

A high level of detailing was required for this scheme.

Approval for this scheme was required from the Engineer acting on behalf of the Estate.
