The Peak was built to replace two previous Victorian office blocks, as part of the rejuvenation of the City of Westminster. Consisting of 11,280m of prime location office space spanning nine storeys, the Peak is a key commercial outlet in the heart of London.

Bourne Steel supplied and erected the structural steelwork (beginning on the upper basement level), metal decking and intumescent coatings.

The perimeter columns were spaced at 7.5m intervals and one member at ground floor was installed as a raking column. All foundation and steelwork had to be diverted around a disused substation.

The mezzanine was hung from the second floor, whilst erection of the under slung introduced some complexities to the steelwork, as the first floor had to be supported on temporary columns and jacks. Oversailing the entire structure is a large curving roof, formed by a series of tubular arched sections, clad with louvers.
