The Carlyle Group has signed engineering consultant Arup to 20,000 sq ft at Three Piccadilly Place in Manchester on a 10-year lease.
Arup will relocate from Bruntwood's St James' Building in Oxford Road, which has been home to the engineering firm for the past 40 years.
At Three Piccadilly Place, Arup will occupy the sixth floor and join Weightmans, EC Harris, Orega, NHS, and Egencia in the building originally developed by Argent.
Ben Du Boulay, director of the Carlyle Group, said: "Arup's decision to move to Piccadilly Place is a great endorsement for the quality of the space on offer at the scheme and strength of the location, which we believe makes it one of the most attractive office destinations in Manchester."
Chris Cheap, director of property consultant GVA, acted on behalf of the Carlyle Group. He said: "Ove Arup had the choice of a number of schemes within the city but were clear that, if they were to leave their long-established base on Oxford Road, it would be to relocate to an office development which offered first class accommodation, the best quality working environment for their staff, and was a move which future proofed their business from a sustainability point of view. Piccadilly Place delivered on all counts and we are delighted to welcome them to the scheme."
Savills and GVA are joint advisers to the Carlyle Group. Strutt & Parker advised Arup in the deal.
