Beneath a Royal Park.
In the spirit of looking at possible options, we investigated the potential for developing a station underneath one of the central London Royal Parks. We looked at possible sites in Green Park, Hyde Park and Regent’s Park. We envisaged using a cut and cover methodology so that the park would be reinstated after construction with the only visible structures within the park being a station entrance, associated access provision, emergency exits and the vent shafts that would be necessary to provide ventilation and a means for smoke to escape in case of fire. Construction of this nature in a green-field site poses relatively few engineering issues, mainly associated with aligning the underground box to fit with existing tunnels. Of the Royal Park locations, Regent’s Park offered better connectivity than Green Park or Hyde Park. This option had made it through stage one on the basis that we required further information from a planning and sustainability perspective.
Gaining permission to build in any Royal Park would require a significant shift in the protection afforded to these sites, which have remained largely unchanged for nearly 200 years. We took the view that further consideration of a terminal station in any Royal Park should only be undertaken as a matter of last resort. We recognise that there would be significant opposition to building in these open spaces that have been safeguarded for the enjoyment of Londoners and visitors alike and which are London landmarks. We therefore concluded that no options to build beneath the Royal Parks should be taken forward.
