Snøhetta's Shanghai Grand Opera House Opens on the Huangpu

A spiraling white roof rises over Shanghai's Huangpu River waterfront, where Snøhetta's 146,786-square-meter Grand Opera House made its public debut on October 17.

The waterfront venue sits in Expo Houtan, a former 2010 World Expo site, and caps a decade of design since Snøhetta won an international competition in 2016. The 4,200-seat building brings three performance halls, production facilities, and publicly accessible spaces under one continuous form. Snøhetta partnered with ECADI, Theatre Projects, and Nagata Acoustics on the project.

What does the building contain?

Three auditoriums anchor the program:

• Harmony Hall — 2,000 seats, the principal venue for grand opera
• Soar Theatre — 1,200 seats, sized for mid-scale productions
• Open Stage — 1,000 seats, configured for experimental work with adaptable stage and seating

Rehearsal rooms, production back-of-house, exhibition galleries, restaurants, and education facilities wrap those halls.

How does it work as a public space?

The roof does the heaviest civic lift. A spiraling staircase pulls visitors from the ground floor up through the roofline to an observation deck that faces the river and the Pudong skyline.

Below that rooftop terrace, public corridors thread between the auditoriums, letting people wander through lobby and amenities without a ticket. A radial landscape, set out in response to the building's geometry, ties the opera house to the adjacent park and waterfront promenade.

Passive design strategies, daylighting, and landscape integration address the project's environmental performance and energy demand. Inside, the material switch happens at the threshold. Harmony Hall wears dark red with sculptural surfaces tuned for opera acoustics. The lobbies and circulation zones run mostly white, opening to daylight through expansive glazing.

That public-versus-performative contrast runs through the entire interior.

What does the opening change for Shanghai?

The opera house anchors Expo Houtan, a former 2010 World Expo site that city planners have been reshaping for years. The debut launches "Born to Sing," an inaugural season running through February 20, 2027, and coincides with the 25th China Shanghai International Arts Festival.

Those twin events position the building as both a civic anchor and a touring-production hub for Shanghai's evolving waterfront.

Snøhetta's opera-house pipeline stays full. The Busan Opera House, commissioned after a 2012 South Korean competition, continues to rise along that city's North Port with a 2027 opening in view.

In Toronto, Snøhetta and Hariri Pontarini Architects will connect the existing Pods and the Cinesphere of the Ontario Science Centre with elevated walkways across a 400,000-square-foot expansion.

In Beijing's Tongzhou District, the firm is working with the Beijing Institute of Architectural Design (BIAD) on the Beijing Art Museum. That project broke ground in December 2025 and is expected to open in 2029.
