ASWS’s steel windows shine the light on award-winning London arcade redevelopment as shopping starts again

The UK’s leading specialist in the refurbishment of steel windows and doors, Associated Steel Window Services (ASWS), is proud to have been involved in the detailed restoration and conservation of both timber and steel fenestration throughout three floors of Quadrant Arcade, a Grade II listed building in London’s Regent Street.

And, as the world starts shopping in London again, the building is one of those which illustrate the beauty of the West End buildings.  (* The building topped the retail category in the New London Awards in 2019.)

The property is part of the Crown Estates portfolio and provides space for many well-known shops in this central and prominent location, with the project being led by Barr Gazetas, while ASWS carried out the extensive work to the street frontage, as well as windows within a large light-well and the reproduction of period ironmongery.

Having suffered from exposure to the weather and been subject to past alterations, much of the detail to the arcade’s fenestration had been compromised, leading to ASWS carrying out a full initial survey before engaging further with Barr Gazetas to help determine the appropriate interventions. In the case of the large street level and first floor windows, which are up to 1900mm tall, this involved their removal to the specialist contractor’s London premises for shot-blasting, repair and treating with a maritime primer.  Due to its condition, the historic glass was replaced and the frames were installed back in the façade before receiving their final paint finish in-situ.

ASWS also restored five small pane steel windows facing into the central light well, as well as replacing four heritage timber windows and a pair of heritage steel windows.  Along the shop fronts inside the 12,000 square foot arcade, ASWS’s highly experienced craftsmen replaced rotten sections of timber frames, including mullions.

Katrina Howard of ASWS commented, “As a specialist in renovation, we are well known to the leading architectural practices, and can advise on suitable solutions.

Here, we worked across the ground, mezzanine and first floor, not just repairing and replacing steel and timber frames, but also sourcing all of the required replica brass ironmongery, which we then re-patinated so that the colour matched throughout the building.”
