A's unveil space-age rendering...

The Oakland A's revealed design plans for their proposed 33,000-seat Las Vegas stadium on Monday, and they're like nothing you've ever seen before — not for a baseball stadium, at least.

The design, credited jointly with BIG Architects and infrastructure engineering firm HNTB Corporation, features an enclosed stadium with a giant window overlooking the Las Vegas Strip with a direct view of New York-New York and the MGM Grand.

It features a multi-piece roof with overlapping layers that are drawing comparisons on social media to one of the world's most iconic buildings. In some ways, from certain angles, the rendering looks very much like the Sydney Opera House ... from the outside, at least.

The interior is all its own, with renderings showing the underside of one of the roof's layers emblazoned in A's green and housing a massive video board stretching across the entirety of right field. Per the A's, the roof's five overlapping layers with gaps for natural light are "inspired by traditional baseball pennants." The proposed 18,000-square-foot video board would be the largest in MLB.

HNTB, which would be credited as the architect of record, designed the Raiders' Allegiant Stadium.

When will ground break on the new stadium?

That's not clear. Monday's announcement didn't include a date. Per MLB.com, "the A’s will continue to collaborate with local partners and navigate approval processes, making refinements to the ballpark design over the next year."

The franchise has cleared several hurdles for its intended move from Oakland to Las Vegas, including receiving approval from MLB owners and state and regional governments in Nevada. It also reached agreement to build the proposed stadium on a 35-acre plot on the south end of the Las Vegas strip at the current site of the Tropicana hotel and casino.

But the actual move has yet to be set in motion. When MLB approved the proposal, the A's stated that they planned for the upcoming season at Oakland Coliseum to be their last, with the expectation to move to Las Vegas in time for the 2028 season. The team's lease in Oakland expires at the conclusion of the 2024 season.

Where they'll play in between remains unclear. Sacramento and Salt Lake City emerged as reported options in February, with Sacramento as the reported front-runner, according to The Athletic, but nothing has been confirmed.
