One Angel Lane sits on a significant site fronting the river next to Cannon Street station. The northern edge of the site is the line of the Roman wharf, and the ‘Steelyard’ under Cannon Street station was a medieval German Hanseatic trading post, the largest in Britain. The strategic viewing corridor to St. Paul’s Cathedral informs the height and massing of the new building. Twin rectangular blocks to the north are attached by an atrium, and the forms of the lower pavilions enclose a southfacing open square.
This, together with the pedestrianisation and widening of Angel Lane to the east, more than doubles the existing public space and creates the largest riverside square in the City of London. In order to enjoy the views, the building is clad in highperformance glazing, using dot-matrix glass with a palette of colours derived from a pixilated image of the water to create a dappled façade.
The lower waterside buildings have clear glass cladding protected by a massive five-storey timber structure redolent of historic wharf structures and responsive timber louvres, which protect the lower pavilion. Intrinsic to this development is the re-use of a third of the existing buildings, utilising the below ground imperial structure to support the new metric column grid above. This results in less demolition and significant savings in time, energy and materials. Roof terraces allow building users to enjoy the riverside setting, while high-level sedum roofs encourage wildlife to inhabit the city.Location: Cannon Street station, UK Architect: Fletcher Priest Architects
