Cundall successfully completed work on the fit-out of ISG Group’s new London headquarters building at 33 Aldgate House at the edge of London. 

As one on the UK’s premier fit-out specialist, ISG handpicked a professional team to deliver an award-winning scheme that reflected their corporate personality as well as showcasing their expertise. ORMS architects were commissioned for the design of the fit-out works of the floor plate and basement.

The majority of the 1974 buildings services, whilst having been replaced, delivered no more than the original installation. Prior to commencing the fit-out, Cundall undertook a comprehensive due diligence of the building services and a validation of the air side commissioning.

Cundall’s services brief included upgrading the primary floor services including:

  • VAV air conditioning
  • Water services
  • Drainage
  • Lighting
  • Power
  • IT infrastructure
  • Data communications to support the new café/ food prep area, directors offices, communications room, reception and meeting block as well as general open plan office requirements.


In addition to delivering these services, ISG wanted our assistance to achieve a ‘very good’ BREEAM rating for the management and design elements.

A supplementary fresh air ventilation system was installed to alleviate demand on the base build system and this served the meeting block; café/food preparation area; and some smaller ancillary areas. New lighting was also installed throughout the floor plate to ensure an LG7 compliant solution.
