New renderings have emerged of the recently commissioned stadium of National Football League (NFL) franchise the Los Angeles Rams, which features a vast swooping roof designed by architects HKS.

In January 2016 the team – formerly known as the St Louis Rams – was granted NFL permission to relocate from Missouri to LA, where it played before 1995.

The Rams will begin playing at their new US$1.86bn (£1.3bn, €1.69bn) stadium in Hollywood Park, Inglewood in 2019.

The 80,000-capacity ground will form part of a new mixed-use development which also features a hotel, retail space, a possible branch of the NFL Hall of Fame and a man-made lake.

The new renderings, published on the Rams’ website, give a first hint at the scale of the lightweight, semi-transparent roof, which will be twice the size of the arena it covers.

They also reveal the lake and a tree-lined public park surrounding the ground’s perimeter.

In moving to Los Angeles, the Rams turned down US$150m (£103.7m, €138.6m) of public money from Missouri to build a US$1.1m (£760.5m, €1bn) development in St Louis.

Owner of the franchise, Stan Kroenke, said the deal had been “multi-years in the making”, but added that the move from the Missouri city would be “bittersweet” due to opposition from some of the team’s fans.
