Helsinki Expo and Convention Centre completes first phase of Solar extension

The Helsinki Expo and Convention Centre has completed the first phase of its Solar extension project. This milestone includes the opening of a renewed southern main entrance at Messuaukio square, which will be utilized starting with the SSIEM 2026 Congress and the upcoming Habitare design fair.

Designed by Davidsson Tarkela Siren Architects, the Solar extension is a glass-structured building intended to be one of the most modern event spaces in the Nordics, featuring contemporary digital surfaces. The project, valued at approximately 20 million euros, is being implemented in alliance with YIT. The full completion of the facility is expected in autumn 2027.
