Cannon Street

The extension to these existing City of London offices on this tight site in Cannon Street involves the design and construction of an independent six storey steel frame, supported by new piled foundations.

The works also include major structural refurbishment to the existing frame including the provision of a cantilevered floor slab around the perimeter to increase net floor area, accommodating service risers and a new glazed facade to all elevations.

Early works included liaison with the Museum of London archaeological services regarding the construction of the new foundations and their impact on possible buried Roman or medieval structures.
