Flashback: Delvendahl Martin Architects' refurbishment of historic 30 Cannon Street in London

Locally based Delvendahl Martin Architects renovated London's historic 30 Cannon Street, an office building originally designed by Whinney, Son and Austen Hall and completed in 1977. With a distinctively patterned glass facade, 30 Cannon Street was added to the National Heritage List for England in 2015, as one of 14 post-war office buildings. The renovated project recently earned a spot in the shortlist of the competitive RIBA 2017 London Awards.

Project description: “The project at 30 Cannon Street was a comprehensive refurbishment that involved the sensitive rejuvenation of a listed building from the late seventies, bringing the office spaces up to current standards and considerably improving the working environment provided. The scheme included the reconstruction of the 5th floor as well as a new roof terrace, and refurbishment of the elevations and entrance lobby. 

Designed by Whinney, Son and Austen Hall, it was the former headquarters of Credit Lyonais and was the first building in the UK to use glass reinforced concrete facade panels developed by Pilkington and Arup.”

“Our scheme included the reconstruction of the 5th and refurbishment of the 3rd floors to incorporate additional space as well as a new accessible roof terrace, with views of St Paul's, and the refurbishment of the main entrance lobby and new lift access to the roof garden. All the GCR panels were re-coated, and the windows re-glazed as part of our refurbishment.”

“The site sits within the St Paul’s Heights Policy Area which, while it imposed limitations to the extension, it also offered the opportunity to improve the view from the Golden Gallery at St Paul’s and simultaneously the outlook from the building’s roof terrace of the cathedral, the City of London, Tate Modern and beyond. The terrace was designed to provide an accessible recreational space and to contribute to the biodiversity of the area.”

“By using the existing conditions and limitations to drive and inform the design whilst simultaneously seeking to enhance the working environment, the built heritage of the City and the building itself, 30 Cannon Street makes a considerable contribution to London’s economy.”
