The firm will oversee construction of a new office development spanning 3,271 sq m.

The existing buildings will be demolished down to basement level to make way for the new high-quality building, incorporating retail units and office accommodation.

The Pall Mall façade will be retained and renovated, with sections being carefully dismantled from site to be cleaned and stored before reinstallation.

Work will see the construction of a new building comprising of basement, ground, and seven storeys. The existing foundations and basement will be reused to reduce embodied carbon, while the new construction uses Cross Laminated Timber (CLT) floor slabs.

Tony O’Farrell, Operations Director at RED Construction London, said: “This key project at the heart of London’s Pall Mall is a prime example of RED Construction London’s expertise in reimagining iconic historical buildings for modern-day commercial use.

“The development of 55-58 Pall Mall and 1-4 Crown Passage will call on our team’s experience in the retention and restoration of heritage features, as we reinstate the building’s impressive façade. We are delighted to have been appointed and look forward to working with the brilliant team across this project.”

Edward Sneddon, Partner at Simten Developments, Development Managers for the project, added: “This is a hugely exciting project that seeks to deliver a cutting-edge building of the highest quality but in an extremely sustainable way. RED Construction London’s track record speaks volumes, and we are proud to be working alongside the team on this scheme.”
