HS2 has submitted designs for a major new building in Burton Green which it says will be "crucial" in helping maintain the new railway line.

Plans show the 'Burton Green Portal Building' will be positioned near the eastern end of the green tunnel, which is currently being built.

It will be 67 metres long, 20 metres wide and 8.8 metres tall, and will house "mechanical, electrical and plumbing systems".

A new maintenance road around the line will also be built.

Constructed with precast concrete panels, the building will also have "a green roof system" to help "minimise the visual impact of the building, provide better control of surface water and prevent solar heat gain".

The application to Warwick District Council explains: "Overall, Burton Green Portal Building is deemed necessary with regards to operation and maintenance of the HS2 line, as well as staff and passenger safety in the event of an emergency on the HS2 line or along Burton Green Tunnel."

The HS2 Act decrees the building will be built, with the council only able to comment on elements of its design.

The high speed rail developer is already well underway in building the 'cut and cover' tunnel at Burton Green.
