We were commissioned by British Land to undertake the extensive redevelopment of this significant building in a prime location adjacent to Liverpool Street Station. As well as providing an exemplary new office building, this multiple award winning project improves connectivity to the Broadgate estate and station, and reinvigorates the surrounding public realm with enhanced retail.

We stripped the 1980s building back to its structural frame, relocated cores to the perimeter of the building to create more open and flexible office layouts, and created a new central atrium.  The tired 1980s cladding is replaced with a sinuous glazed façade to create a modern identity befitting the building’s size and location. A new rooftop restaurant and large external terrace on the 9th floor offers fantastic views across the city to St Paul’s Cathedral.

An additional three floors of office accommodation were created whilst retaining the existing foundations and a large proportion of the existing steelwork, thereby significantly reducing the embodied carbon in the new building and allowing the Network Rail retail areas below to continue trading throughout construction. The development creates a total of 520,000 sq ft of lettable office space. 

We developed interior concepts in collaboration with Universal Design Studio with an emphasis on welcoming, flexible spaces for building users and visitors alike. 

The top five floors of the building are progressively setback to reduce massing viewed from the tight grain of the City streets, and to create outdoor amenity and a series of planted  terraces. New escalators and pedestrian walkways inserted into Octagon Mall improve permeability through the scheme and creating a dramatic entrance to Broadgate for passengers emerging from Liverpool Street station. 

100 Liverpool Street achieved BREEAM Outstanding rating and WELL Gold certification.
