What the view from the new roof terrace will look like

The refurbishment, designed by US practice Gensler, was given the green light by the City of London corporation at the end of September.

It will see the construction of one extra storey housing office amenity space and the creation of a 5,000 sq ft rooftop terrace, including a 2,700 sq ft rooftop pavilion with views over the City and St Paul’s Cathedral. 

The scheme aims to “create an intervention that brings softness and greenery to an otherwise rational, high-tech, very modern structure, ”Gensler said in planning documents.

Foster & Partners was appointed to design the seven-storey building in 1996 and it was completed in 2003.
