HSL is a joint venture between The Doctors Laboratory, University College London Hospitals NHS Foundation Trust, and the Royal Free London NHS Foundation Trust.   

The new 133,000 sq ft laboratory in the former Unison HQ between Euston and King’s Cross stations, now known as the Halo building, will see the organisation consolidate facilities to form one of the largest pathology laboratories in Europe. 

Halo building at 1 Marbledon Place will be home to Europe’s biggest pathology laboratories

ISG will work across five basement levels of the building, along with a further 10 storeys above ground.

The multi-phased project begins with the Cat A fit-out of the ground and basement areas from shell and core, including the installation of the building’s complex mechanical and electrical services infrastructure.

During this phase, ISG will also undertake technically demanding structural works at all levels to accommodate heavy medical and research equipment.

ISG will then commence the Cat B fit out of the building, including highly specialised containment level 3 facilities, which are suitable for research and testing of contagious and life threatening viruses.

The CL3 laboratory involves the installation of custom-designed ventilation services, with HSE-approved air locking systems.

The contractor will also create a number of specialised laboratories, as well as the largest automated blood sciences laboratory in the UK, to expedite efficient processing of a wide range of pathology testing services. 

Paul Sharp, divisional director of ISG’s Engineering Services business, said: “This is a flagship project of national and international standing.”
