Number 1 Undershaft will be the tallest building in the City of London. The external weathering steel cross bracing works in combination with an offset concrete core housing the main building lifts and escape stairs. The perimeter steel superstructure columns are supported on a series of transfer structures so that the building rests on just eight columns at ground level.
The MEP design for 1 Undershaft needed to both inform and enable the architecture. The unique base of the tower, with its open space and lack of basement, required a different approach for housing everything from the chiller plan to the VTS without compromising the building aesthetic or impacting on floor plates.
This presentation discussed how the design of the structure and building systems evolved to meet the constraints of the site and the aspirations of the architectural concept.
