Project Description

The Channel 4 headquarters building is an iconic example of high-tech architecture and the entrance atrium is a standout feature using groundbreaking structural glass technology. 25 years later the façade needed significant refurbishment due to aging and damage. The project successfully restored the original façade with minimal changes, respecting its historical importance and architectural integrity. The engineers adopted a conservation design philosophy, aiming to retain the building's iconic status while enhancing safety and durability.

Judge’s comments

The careful retention and refurbishment of an architecturally significant glass façade. The structural engineers were integral to the success of the project, applying a minimal intervention approach to the intricate historical preservation.
 
The original glass was carefully replaced with laminated glass, providing greater post-breakage robustness and reducing solar heat gains. This upgrade ensured that the façade met current health and safety standards without compromising the original aesthetic.
 
A detailed appraisal of the existing structure was undertaken, as well as sophisticated analysis of the structural system, and meticulous planning for disassembly and refurbishment. These efforts ensured the safe and effective restoration of the atrium. Data visualisation and dashboards ensured clear communication and informed decision-making throughout the project.
