The move comes on the back of a near doubling of Turner & Townsend’s London revenues in the past five years.
More than 1,000 staff will be based in the new London office, sharing a single 3,800 m2 (41,000 sq ft) floor plate.
UK managing director Jon White said: "In the last five years our London office has increased its revenue by 84%, and as the business has grown, so too has our capability and our ambition. In the past year alone we have increased our London headcount to more than 1,000 people.
"Our new home at One New Change will have substantially more space than our premises at Savoy Court, and will give us the freedom to continue expanding. The new office is also closer to the London bases of many of our global clients, and is laid out on one floor, with more open and flexible space.”
