BBC Sport - West Ham: Olympic Stadium will have 'dramatic atmosphere'

Roof started at West Ham's new home

The acoustics at the Olympic Stadium will "be like a cathedral" when West Ham United move to the ground at the start of the 2016-17 season.

The first panels of the stadium's new roof were lifted into place on Friday, as the construction team start to build one of the largest cantilever roofs in the world.

Mark Craine, an architect at Populous, tells BBC London's Sara Orchard there will be a "dramatic atmosphere" at the Premier League club's new home.
