The building was designed to sit well within its context, and it comprises two forms: a 7 storey building fronting onto the Minories, and a 16 storey glass tower to the rear which steps back from the north at 12th floor level and from the west at 13th floor level. Our design which was approved by City of London Corporation Highway Engineering Division, basically entailed constructing a “box within a box”. The engineered design process on–site was to install trust blocks at various strategic locations, temporary prop the existing liner walls, cleanse the basement substructure for obstructions and partially infill the existing basement. All of these processes were in parallel with onsite archaeological excavations including the “Roman eagle” statue.
The scheme uses a number of intelligent building systems to help achieve a BREEAM Excellent rating. These include the design of highly thermally efficient facades with just 35% glazing; heat recovery systems; and green roofs to help thermal efficiency and to mitigate rainwater run–off.
