Sixers, Flyers unveil first renderings for new arena on the old Spectrum site

The Sixers and Flyers officially have a face for their future home.

This week, the Sixers and Flyers dropped the first exterior renderings of the new arena going up in South Philly, built right on top of the old Spectrum footprint. The building will sit next to Xfinity Mobile Arena, which replaced the Spectrum back in 1996 and is still standing in the same stretch of the Sports Complex.

Target opening is spring 2030, timed to have the building ready before Philly’s incoming WNBA expansion team tips off its first season.

No relocation drama here. The Sixers are staying in South Philly, just moving next door. The new arena goes up in the western part of the Sports Complex, on the old Spectrum site, while Xfinity Mobile Arena keeps running until the new building is finished.

This is a Flyers story too. The Spectrum is where the Flyers played from 1967 to 1996 and won both of their Stanley Cups, so this is the franchise moving back onto the ground that made it.

The design leans hard into Sixers and Flyers history

The renderings show three stacked, cantilevered “bands” wrapped around the exterior, a direct callback to the old Spectrum’s look. Outside, there’s more than half an acre of plazas and gathering space, plus a wide staircase built to echo the Art Museum steps. Yes, the Rocky steps. Philly sports architecture with an actual sense of place, for once.

Who’s paying for it and who’s building it

The arena is a 50-50 partnership between Harris Blitzer Sports & Entertainment, which owns the Sixers, and Comcast Spectacor, which owns the Flyers and Xfinity Mobile Arena. It’s fully privately funded, though the project’s cost hasn’t been made public.

Populous and Moody Nolan are designing the building. A Turner/AECOM Hunt joint venture is building it. Levy is already locked in as the food and beverage provider. Naming rights belong to Comcast Spectacor and will get announced separately down the line. Comcast Spectacor is also working with the Phillies on developing the real estate around the arena, though nothing about that piece has been detailed yet.

The pitch: jobs, money, and a “new era”

The Sixers and Flyers are calling this the largest fully privately funded project in Philadelphia history. The two sides are projecting close to 15,000 jobs and nearly $6 billion in economic activity over the next decade, plus new tax revenue for the city and the School District of Philadelphia.

Comcast’s Brian Roberts, Sixers managing partner Josh Harris, NBA commissioner Adam Silver, and NHL commissioner Gary Bettman all showed up with the same talking point: new era for Philly sports. Whatever you think of the ownership group, the building itself looks like it was designed by people who actually know what city they’re building in.

Spring 2030 is still a long way off. But for the first time, the Sixers’ next home has an actual face, and it looks like South Philly.
