The £400m project involves redevelopment of the 5.5-acre former St John’s Wood Barracks, previously occupied by the King’s Troop, Royal Horse Artillery.

McGee is currently on site overseeing piling, excavation, reinforced concrete, and installation of bearings on the five-acre basement ahead of main construction work on  nine buildings ranging in height from three to six storeys containing 179 homes.

Permasteelisa will design, engineer, manufacture and install over 15,000 sq m of custom-made architectural cladding across all blocks.

The design phase of the work has already begun at Permasteelisa’s design centre in Italy, where the bespoke elements of the façade will also be assembled in its specialist manufacturing facility.

On site work will start at the end of this year with scheduled completion of the façade works planned for the summer of 2026.

Liam Cummins, Permasteelisa Group’s CEO, said: “We are proud to have been chosen for such an exclusive project as St. John’s Wood Square which, due to its size, logistic complexity and challenging timeline is the ideal project to further demonstrate our ability to meet the needs of our customers’ expectations.”

Nicola Calzolari, Executive General Manager for Permasteelisa in Italy, added: “This new contract confirms once again the strategic importance of the London market for Permasteelisa.

“For St. John’s Wood Square, our team in Italy is responsible for the delivery of the entire design and production of the customised façade elements, whilst our colleagues in the UK will ensure the efficient management of all on site activities.

“We are already enjoying our work on the design phase and our UK colleagues look forward to starting the installation on site by the end of the year and to seeing the project façade works successfully completed by summer 2026.”
