The roof of Birmingham New Street has been completed, as the £600M revamp of the station takes shape.
The transparent ETFE (ethylene tetrafluoroethylene) plastic bubble roof will bring more light to the concourse and atrium areas.
The material has also been used on the Eden Project in Cornwall, the outside of Bayern Munich’s Allianz Arena, and the Beijing National Aquatics Centre.
The final piece of the station’s new atrium roof covering was put into place on 16 September.
Chris Montgomery, Network Rail’s project director for the Birmingham New Street project, said the translucent roof covering will allow natural light to stream down through the atrium onto the huge new concourse below.
However, 6,000t of concrete will have to be removed from two floors of the old Pallasades shopping centre first. Demolition contractor Coleman is carrying out the work.
Montgomery said: “Piece by piece, the design and concept for the station is being brought to life and it’s great to see the last section of the new roof covering lifted into place.
“Completing the atrium structure and covering it in its Eden Project-like material is a real milestone but we’re already looking forward to the next step. Demolishing part of the former Pallasades will flood the new concourse with natural light from above, transforming the experience of millions of passengers who will use this fantastic new station when it opens in about a year’s time.”
Transport Minister Baroness Kramer said: “Birmingham needs a station that reflects the city’s growing reputation as a strong, vibrant and modern city and I am confident that, with just over a year to go before the work is complete, New Street will deliver that.
“This is a great achievement and a fantastic example of how the £38bn being invested in the UK’s rail network, as part of our long-term economic plan, is making real improvements for passengers.”
