Permasteelisa Group, the global leader in the design, construction and installation of technically advanced building envelopes, has been appointed to deliver the glazing and cladding at St. John’s Wood Square, a prestigious new development in the heart of London.

The St John’s Wood Square project is the redevelopment of the 5.5-acre former St. John’s Wood Barracks, previously occupied by the King’s Troop, Royal Horse Artillery. The residential development will comprise nine buildings, ranging in height from three to six storeys, offering a total of 179 residential units.

Permasteelisa will design, engineer, manufacture and install over 15,000 sq m of custom-made architectural cladding across all blocks. For the main elevations, largely made up of precast elements, the company will supply tripled glazed punched windows and sliding doors, balustrades and metal balconies.

In addition, specific elements will be provided for the wrap-around glazing, roof mansards and external ‘veil’ structures that slope against the vertical walls within the penthouses, as well as the glazing that will occupy the ground floor on the street front.

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 2024, with scheduled completion of the façade works planned for the summer of 2026.

Liam Cummins, Permasteelisa Group’s CEO, comments: “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, adds: “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.”

John Conboye, Executive General Manager for Permasteelisa in the UK, adds: “Being part of this prestigious scheme will add to our already impressive portfolio in London. As a Group, we have delivered many of the capital’s iconic developments including The Shard, 22 Bishopsgate, 20 Fenchurch Street (a.k.a. the Walkie Talkie building) and significant residential projects at Battersea Power Station.”
