The extension project at Helsinki Expo and Convention Centre in Finland, the next-generation event venue Solar, has reached its topping-out stage.

Once completed, Solar will be one of the most modern event venues in the Nordic countries.

Rising on Messuaukio square, Solar will be completed in August 2027. The event venue is being built by YIT.

Helsinki Expo and Convention Centre is carrying out one of the largest investments in Finland’s event industry. Solar, once open, will host international corporate events and congresses, seminars, general meetings, product launches, celebrations and gala events,.

“Solar will take events to a new level. It is not merely a new building, but part of a broader vision. Our goal is to strengthen Helsinki’s position as a destination for international events and to create an environment where events can deliver even more impactful experiences for participants,” said Veronica Lindholm, CEO of the Finnish Fair Corporation.

Solar will also offer event organisers new venue configurations and event settings.

“We want our customers to experience a real wow factor the moment they step into Solar. Around €20m will be invested in Solar, making it one of the largest development projects at Helsinki Expo and Convention Centre,” Lindholm added.

With a growing demand for venues where digital solutions support both the brand experience and the overall event experience, Solar’s digital solutions are not separate services but an integral part of the venue’s infrastructure. The event venue will feature 350sqm of digital display surfaces across 14 screens, while the lighting system will include 70 moving lights.

The architecture is also one of the venue’s defining characteristics. Designed by Davidsson Tarkela Siren Architects, the venue is distinguished by its extensive glass façades and open, airy design and rises to a height of more than ten metres.
