The piazza in front of the Euston Station concourse is the roof structure to the underground car park.

The scheme involved the re-paving of the piazza and the introduction of new retail units which needed to be designed to be lightweight to minimise and spread the loadings. 

Euston Station is due for major redevelopment within the next decade and therefore the retail units were also designed to be modular to speed up the installation and thereby maximise revenue over the short design life.
