Developer Derwent has now signed off the main contract – worth £195m – as preliminary works continue at the site.

The mixed use scheme will contain 209,000 sq ft of offices, 36,000 sq ft of retail and a 40,000 sq ft theatre. It is due for completion in November 2021.

Laing O’Rourke was also main contractor on the construction of the Tottenham Court Road Crossrail Station.

Liam Cummins, Head of UK Building for Laing O’Rourke said: “We look forward to delivering Soho Place, further strengthening our partnership with Derwent London.

“This will be a landmark project, sitting at 1 Oxford Street, and interconnected with the Crossrail upgrades to Tottenham Court Road, which we are also delivering.

“Laing O’Rourke has the ability to drive certainty into the delivery programme through our in-house capabilities along with a fully integrated supply chain and advanced digital engineering and offsite manufacturing.

“The project is in total alignment with our 2025 mission to be the recognised leader of innovation and excellence in the construction industry.”

Richard Baldwin, Head of Development of Derwent London, said: “We are very excited about the prospects for Soho Place, which will be a great building in one of the best locations in London.

“We are also very pleased to be working with Laing O’Rourke, who we believe have the capabilities to deal with the complexity of the site.”
