2,000 years of history. One complex build. The next chapter for Holborn Viaduct.

2,000 years of history. One complex build. The next chapter for Holborn Viaduct.

Multiplex has reached practical completion at Holborn Viaduct, marking the end of a remarkable construction journey in the heart of the City of London.

Developed by Royal London Asset Management and designed by PLP Architecture, the 13-storey development will become the new London headquarters of Hogan Lovells. The project has achieved BREEAM Outstanding with a 92% design-stage score and WELL Platinum (Shell & Core), with a NABERS 5-star operational energy target. 

The history and character of the site have shaped the project from the outset. During excavation, Museum of London Archaeology (MOLA) uncovered a significant Roman cemetery, including five oak coffins, jewellery, a Roman oil lamp and the first complete Roman funerary bed ever discovered in Britain. A selection of finds will be permanently displayed within the completed building. 

Alongside preserving the past, the team focused on reducing the carbon impact of construction. Working closely with Heyne Tillett Steel and BHC, Multiplex incorporated 80 tonnes of reused structural steel, replaced around a third of cement-based products with lower-carbon alternatives and reused 33% of the existing Portland stone. 

To mark practical completion, our new film, Discovering the Past: Building the Future, takes you behind the scenes of the project, exploring the people, expertise and stories behind Holborn Viaduct. From the archaeology uncovered beneath the site to the innovative construction solutions delivered above ground, the film looks at how collaboration across the project team helped navigate a uniquely complex build.
