Video | Roof takes shape on Birmingham New Street redevelopment

The £600M revamp of Birmingham New Station has reached a “significant milestone” with the installation of the first roof sections.

A transparent ETFE (ethylene tetrafluoroethylene) plastic bubble roof is being constructed which 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 team working on the new station and Grand Central retail development have secured the material over the first sections of the steelwork which will form the roof over the atrium.

Network Rail project director Chris Montgomery said: “The first pieces of cladding being attached to the atrium roof is a significant milestone in the building of the new station and Grand Central development.

“The specially designed sheets will be fitted to the structure over the next few months and will become an instantly recognisable part of the Birmingham skyline.

“Once the structure is completely waterproofed, we will be able to start the demolition of the floors beneath it to create the impressive atrium which will allow natural light to fill the station concourse for the first time.”

Network Rail describes ETFE as a “translucent material [which] is strong, durable, has a high corrosion resistance, is self-cleaning and recyclable. It is also much lighter than glass.”
