This comprehensive redevelopment has become one of the most sought-after City office addresses of its type. Every aspect of what had become a tired and outdated structure has been reviewed, redesigned and refreshed – it now offers highly sustainable, column-free, grade-A office space enjoying 360-degree views of the City. By adopting the latest technology, the size of the building’s service core was reduced by 30% to deliver a highly efficient, lettable space ratio. The design also carefully integrates an additional floor, further expanding the net area, while working within the building envelope. The scale, grain and texture of the new elevation work together to establish subservience towards the adjacent presence of St. Paul’s Cathedral, as well as maintaining consistency with the surrounding architecture.
