The Helsinki Olympic Stadium, built in 1938, is an iconic landmark of independent Finland and Finnish functionalism. After 80 years, its core functions – sports and events – have evolved along with the contemporary needs of the facilities. How can the historical stadium function as a modern events venue for sports and culture while preserving its strong heritage? K2S worked on the stadium’s preservation plan with simple forms and expressions. K2S first designed a new wooden canopy for the building in 2005, followed by 20 000 square metres of multifunctional spaces for events and activities, including the visitor centre. The preservation plan included restoration efforts and combining the preserved areas with new interventions, additions and premises.
