Old Street Roundabout

Under Construction

This high profile, pedestrian orientated scheme that converts an existing roundabout island at Old Street into an urban peninsula that provides a gateway space for the underground station.

Known as the silicon roundabout, Old Street is a high profile, pedestrian orientated scheme that converts an existing roundabout island into an urban peninsula. It naturally forms an extension to the tree-lined Promenade of Light and provides a gateway space to the new entrance for the London Underground station. The design explores innovative solutions to promote climate resilience, biodiversity and user experience through a series of designed initiatives that visually and physically demonstrate the integration of green infrastructure within a very complex and demanding space.

Resilient London: confronting climate change

Resilient London: confronting climate change

Known as the silicon roundabout, Old Street is a high profile, pedestrian orientated scheme that converts an existing roundabout island into an urban peninsula with a new entrance for the London Underground station. The design incorporates natural and manufactured climate resilience measures. This includes a flood defence system and the use of materials that enable permeability and provide attenuation, natural interventions like rain gardens and green roof systems also double as a source control mechanism for run-off. This includes photocatalytic paving which uses natural daylight to convert harmful NO2 gases into harmless nitrates that are washed into the rain gardens.
