The granite covered CT Blocks at 20 Fenchurch Street.

Client: 20 Fenchurch Street 

Date: April 2014

Location: 20 Fenchurch Street, London


Also known as the “Walkie-Talkie”, 20 Fenchurch Street has quickly become one of the most iconic buildings in London. Designed by Rafael Viñoly, the skyscraper breaks the rules of architecture by increasing in size near the top of the building rather than the bottom, creating a unique design. The building is occupied mostly by offices, with a spectacular ‘sky garden’ on the top two floors which caters for both office workers and tourists alike.  This design also allowed for more public space at the base of the skyscraper, while providing more premium space at the top.

Project details:

Security engineering consultants QCIC asked Townscape to create a bespoke perimeter security solution which would serve two functions: protecting the building from vehicle attacks and providing a memorable and high quality urban landscape around the bottom of the skyscraper.

The designers behind the plan additionally needed the security framework to be multipurpose and not viewed singularly as a security measure. Working with the leading stone brick work firm Gormley, Townscape created and installed six PAS 68 CT Blocks, which are finished with granite and incorporate LED spot lighting on the sides. The high quality granite finish was chosen to tie into the prestigious City of London environment.


20 Fenchurch Street is shielded from any antagonistic vehicle attacks to the most astounding PAS 68 standard, thanks to Townscape's HVM expertise. Townscape took its leading HMV product, the CT Block, and gave it extra purposes as security seating and lighting for this very special commission. Guests at 20 Fenchurch Street will appreciate the open plaza, uninformed that the seating and arranging has been intentionally designed to give the best security.
