Sydney has been given the first official glimpse at one of the city's most controversial projects, as artists' impressions of the winning Sydney Football stadium design are released.

Sports Minister Stuart Ayres says the design will create "a colosseum of sound and colour" that will "set the standard for rectangular stadiums in Australia".

The stadium will feature a state-of-the-art roof, which will light up from the underside in the home team's colours and reflect noise back into the stadium to amplify the atmosphere.

Mr Ayres says the winning design also pays tribute to the natural surrounds.

"Just like western Sydney Stadium, we've used the natural environment as inspiration in the design, with a striking bronze façade in place that reflects Sydney's unique sandstone geology, and a lightweight cloud-like roof structure," Mr Ayres said.

Cox Architects delivered the winning design, beating two other firms in the process.

Mr Ayres said it would give Sydney the upper hand over the other states when competing for major events.

"This stadium will kick [Queensland's] Suncorp Stadium into reserve grade," Mr Ayres said.

"From technology and design to amazing views, it's nothing short of world class."

'We are all getting a bit bigger'

The architects said the stadium has been designed to accommodate the waistbands of future patrons.

Alistair Richardson from Cox Architects — the architects in charge of the build — said it has been designed to be used for another 30 to 40 years.

"What we try do with these new stadiums, is we try and make sure that they're as flexible as possible to understand where futures are doing (sic)," he said.

He said that includes the shape of seating.

"So seat centers are wider for example, row depths are longer to accommodate the fact that we are all getting a bit bigger," Mr Richardson said.

"So we are trying to make sure that we are building things in."

Demolition works on the existing Sydney Football Stadium are due to start in January and the new stadium will be complete by 2022.

The Government faced a fierce public backlash when it first announced plans to spend more than $2 billion knocking down and rebuilding both the Sydney Football Stadium and the Sydney Olympic stadium at Homebush.

It eventually revised the plan, announcing instead it would refurbish the Olympic Stadium instead of rebuilding it.

But the Government maintained it needs to push ahead with the knockdown of the Sydney Football Stadium because the ageing stadium was a safety risk.
