Mace Dragados JV, HS2’s station construction partner, has worked with the design consortium of Arup, WSP and Grimshaw Architects to refine and value engineer the design to reduce costs.
The original arched station roof has been swapped for an easier-to-build geometric roof design that allows natural light to flood into the 300m long station concourse below.
Elements of the new roof design can be prefabricated off-site, and installed using modular construction techniques, reducing costs, carbon emissions and local disruption.
The HS2 station will be set across three levels, with 10 subsurface platforms that are 450m long.
The station hall – 20% larger than Trafalgar Square – will become the largest station concourse in the UK.
Retail and station facilities will be available on the ground and first floor, underneath the top-lit station roof.
Construction of the HS2 station will also support 3,000 jobs at peak and will offer hundreds of contract opportunities through the supply chain.
MDJV recently began a multi-year procurement of packages worth £500m for work on the HS2 station and the London Underground at Euston and Euston Square which will provide improved connections for passengers.
Taking account of the recommendations of the independent Oakervee review, the design integrates the HS2 station with the existing Network Rail station and emerging plans for over site development, led by Lendlease.
Lendlease, the Government’s appointed Master Development Partner at Euston, has started an 18-month long public consultation to seek the views of the local community about what would be of value to them in the development.
