Grimshaw Architects, in collaboration with Arup, have revealed renderings for their proposed 25,000 square metre High Speed Two (HS2) railway terminal at Euston Station, in north London. They have developed an "incremental staged design" that will allow for the construction of the new high speed station while maintaining all existing services. Fronted by a 38 metre glazed façade, the new entrances will transform the internal circulation spaces into a "light and airy destination with shops, restaurants, and cafés."
The station’s vaulted roof will house eleven new high speed platforms which will be situated below street level. These new platforms will be built in two stages as part of a phased approach to enable existing services to continue operating, resulting in less disruption for passengers. And eleven existing platforms will be retained in the current station, which will serve the existing network.
