22 Bishopsgate
London, England · 2014-2020 (construction of current design) · Not readily available, original project had £500 million shortfall
The judgement call
Account-gated at launchRedesign and value engineering: The project underwent a significant redesign to make it more economical and viable after the initial Pinnacle project stalled. - Focus on occupant well-being: The building was designed as a "people-led smart building" with amenities and features aimed at improving the occupier experience. - Innovative construction techniques: Developed new construction techniques to enhance architecture and suit different building uses.
Key engineering challenges
Reusing existing foundations: Adapting the existing three-storey basement and over 300 piles from the aborted Pinnacle project required complex engineering measures to transfer loads from the new building's core and columns. - Building in a dense urban environment: Construction in the heart of London's financial district presented logistical and site constraint challenges. - Optimizing for sustainability: Designing and constructing a building to meet high ESG standards and achieve net-zero goals.
