Situated adjacent to St. Paul’s Cathedral, our reworking of this six-storey neo-classical building has created 116,000 sq ft of high-quality office space, three levels of communal terraces and a new public garden.

We worked alongside landscape architect Tom Stuart-Smith to create a new garden immediately in front of the building where existing trees have been retained alongside new shrubs and understorey planting that will provide round-year interest and ground coverage to the redeveloped space. In the garden’s centre is a large, reflective pool designed in collaboration with water feature specialist Andrew Ewing. This reflects the sky and surrounding historic environment on its surface and serves as a light-well for the basement space below.

Externally, the re-glazed facade improves the building’s energy performance with enhanced views of the St Paul’s Cathedral, whilst new three terraces across levels four and five provide external break-out spaces with glass balustrades and a roof terrace provide large, flexible space for the building’s users during the day or for events with the Cathedral as a backdrop. The glazing has a contemporary, yet contextual finish and is part of a wider approach to rationalise the building’s outdated neoclassical features.

The newly refurbished 25 Cannon Street is a welcome addition to the Square Mile’s top-quality office, retail and leisure offering. In particular, the City Corporation was pleased to support the new public garden for both workers and visitors to enjoy. With most of the office space already let, it is clear that recovery is well underway, and we hope schemes like this will continue to draw people back into the City post-pandemic.
