Mortgage Matchup Center Modernization
The panel system and rigging grid are suspended from an inner curved ring and an outer perimeter compression ring. A slender cable net supports the retractable panels and all rigging elements and includes a walkable mesh that provides a large, safe working platform for future events.
The acoustic ceiling uses readily available off-the-shelf parts. This simplifies maintenance while helping to control costs.
Every amenity integrates with the sphere’s form and improves its function. Though the exterior remains unchanged, the refreshed interior creates a much more intimate and immersive experience.
Avicii Arena originally opened in 1989 as the world’s largest spherical building. Despite being one of Stockholm’s most recognizable landmarks, the arena was underutilized. An HOK-led design team transformed the heritage building to meet the needs of modern sports and entertainment events while preserving its distinctive form. The comprehensive modernization preserves most of the existing structures and systems while reimagining acoustics, enhancing flexibility and improving the fan experience.
Design Solutions
The design team was challenged to create a completely new experience within the venue without altering the arena’s exterior. The first step? Addressing acoustics.
Akin to building a ship in a bottle, the transformation’s signature feature – a retractable acoustic ceiling — was carefully engineered to fit within the constraints of the spherical structure. Reflective panels, suspended from a “potato chip” shaped inner curved ring and outer compression ring, reduce the building’s volume, optimizing acoustics and improving the atmosphere for events like ice hockey and concerts. A slender cable net supports the ceiling’s infrastructure, while providing staff a safe, walkable mesh platform. The ceiling was thoughtfully constructed with off-the-shelf parts to simplify maintenance and minimize costs. This adaptable system allows operators to tailor the venue’s atmosphere and acoustics for a wide range of events all while dramatically improving sound quality and production capabilities.
The modernization also enhances the fan experience through new premium hospitality spaces and the introduction of gondola seating. These cantilevered platforms, inspired by a similar product at Little Caesars Arena, appear to float above the floor, providing a unique vantage point and intimate connection to the action. A reconfigured seating bowl, upgraded technology and expanded rigging capacity further support diverse event configurations and faster production turnarounds.
Impact
By adapting the existing building rather than replacing it, the project extends the life of a beloved civic landmark while minimizing environmental impact. Avicii Arena once again anchors Stockholm’s entertainment district, providing the city, spectators and performers a revitalized venue that balances heritage with innovation.
