The firm has been contracted by Berkeley Group brand St George to install the mechanical and electrical systems for all 359 new-build apartments within Saffron Wharf.
The block of mixed-tenure apartments is part of a master plan for 1,800 new homes and 180,000 sq ft of commercial space on the 15-acre site of the former News International printworks.
Work on site is scheduled to start in late 2022, with completion of the contract due in early 2025.
Peter Grierson, Managing Director of J S Wright, said: “We are thrilled that our reputation for equipping large residential developments with combined M&E systems to full customer satisfaction has been rewarded with such a prestigious commission from a new client.”
